There is some great advice above, but remember everything you read on this board or others comes from anonymous internet posters mine included so take whatever you read with a grain of salt. I enjoy posting to make people think and I have gone through law school, but remember nobody posting knows you, your situation, or what is best for you.
With that said I will offer some anonymous internet poster advice.
ADMISSION AT THESE SCHOOLS: Check out lawschoolnumbers.com it gives you a more detailed description than LSAC although. As to the schools you listed I would say there is almost no chance of admission. You have listed some very hard schools to get into and the reality is at every ABA school from Harvard down to Cooley law students are smart, hard-working, and motivated. To get into any ABA school you need to finish in the top 50% of LSAT takers and that consists of people that earned a B.A. and got a 3.0 or higher generally. Your score puts in the top 60-65% of a pretty elite group, but there are people that simply did better than you.
LSAT RETAKE QUESTION:I would not hold off your application to retake. This is for two reasons (1) odds are you will not improve. The LSAT is the first of many times on the law school route where you do not perform as well as you expect. If you end up enrolling in any law school on the first day of class 100% of students think they will be in the top 10% and the LSAT was a fluke. Each person will they think they have an edge over everyone else because they having worked in a law-firm, were a cop, a pro-athlete, went to Harvard for undergrad, etc whatever it is 100% of the students will think they have some edge that make them special and they will be in the top of the class. You don't need an A in first grade math to see what happens when 100% of people think they will be in the top 10%. This is why so many student are upset about their first year grades. So your performance on the LSAT is pretty good and probably won't improve and being somewhat disappointed is something all law students need to get used to.
With that said if you wait another year to retake the LSAT life will probably get in the way something at work will come up, you will get married, have a kid, or simply think you will get a 170 on the LSAT the third time you take it. Then you may never end up going.
-Recommendation-So I would advise you to do this if you have just taken the July LSAT send out your apps as planned and then sign up for the October and February LSAT. If you end up scoring a 170 then alter your plan and I believe most schools no longer average your score so there is no penalty and your in an everything to gain nothing to lose scenario. Check with each school though. If you end up getting a 155, 157, etc then your applications are out and you can enroll and you have lost nothing.
LAW SCHOOL GENERAL ADVICE: When choosing a law school many OL's take the rankings, opinion magazines, and anonymous internet poster advice far to seriously. In my personal opinion location, cost, personal feelings about the school, and any specialty program if you know what you want should take precedent over what a for-profit, unregulated magazine, offering an opinion thinks or what some random person on the internet tells you what is best for you.
LOCATION IMPORTANCE TEXAS QUESTION? I noticed you are from Texas and attended Texas Tech and are now considering California schools. Out of curiosity what is bringing this change. No matter what the National Jurist, Above the Law, U.S. News, etc thinks location is going to play a bigger role than anything in your legal education. Law school does not exist in a vaccuum and if you go to law school in San Francisco it is going to be a lot different than Texas. L.A. is massive sprawling city and you will need a car to do anything. These all considerations to take into account. So many OL's just move across country based on what a magazine says is think everything will work out, but you will have time to be a human being in law school.
Furthermore, over 3 years your roots will get dug in. You will get an apartment, get a relationship if you don't have one already, make friends, and most law graduates never end up leaving the city they went to school in. 3 years is a long time and law school years particularly 1L could be counted in dog years it is a long haul. If California is where you want to end up then go to school there, but don't expect it to be easy to just up and move across the country somewhere else.
On top of that if all your family, friends, and so forth are in Texas you are going to miss them. I don't know if that is the case, but as I stated above you will have time to be a human being while in law school. If you go to a new city, you don't know anyone, your struggling to find an apartment in an unfamiliar environment, you don't know your way around, all while trying to grasp the concepts of Covenants, the Rule Against Perpetutities, and so forth it is going to be very hard on you.
I could belabor this point even more than I have, but location is important.
PERSONAL FEELINGS ABOUT SCHOOLI did a lot of mock trial competitions in law school and visited different schools. Furthermore, I visited a lot of schools as a OL. Each school has a culture or feel to it and there were some places I did not like and others I loved. However, that is my own personal feeling and what I liked you may have hated and vice versa. Neither I, U.S News, the National Jurist, and so forth could possibly know what YOU like. So I strongly encourage you to visit the schools, talk to students, talk to professors, admins, and see if YOU like it. This is a life altering decision so make sure you like the school you will be attending.
COST:Despite location or personal feelings costs is important money is money no matter what. If you graduate 150k in debt accruing 8.5 interest it is something to think about. With your numbers you may be able to get scholarships at some schools and getting a debt ABA degree is something to consider.
However, if you do get a scholarship be wary of the conditions on them this NY times article does a good job of explaining why.
http://www.nytimes.com/2011/05/01/business/law-school-grants.html?pagewanted=all . Classic example of law students not understanding that not everyone can be in the top of the class. If you get scholarships ask questions do not assume everything will just work out. All law schools are businesses first and foremost.
REALITY OF LEGAL EDUCATION: Despite what these anonymous internet posters and opinion magazines say law school education is the essentially the same no matter where you go. First year will consist of Torts, Civ Pro, Property, Contracts, LRW, Crim Law, Con Law, and Crim Pro. Or some slight variation on that and in these courses you will read Famous cases. Pennoyer in Civ Pro, Palsgrass in Torts, Hadley v. Baxendale in Contracts, the mud-flap case in Con-Law and this is the case at almost every school I have encountered.
SPECIALTY PROGRAMS:
This does vary from school to school and if you know exactly what you want to do then consider it. If you want to do entertainment law then you should first consider location. Where does entertainment law happen? L.A or New York and therefore schools in L.A. or New York often offer courses in entertainment law and have adjuncts who can teach, because entertainment lawyers live in L.A. or New York.
If you want to do IP law then go to school in the Bay Area that is where the IP companies are and the adjunct professors teach. If you want to do Martime law do not go to Nebraska it's landlocked and therefore will not likely have courses in martime law. Point being again do not leave your common sense at the door when making your law school decision.
If like most law students and lawyers you don't know what you want don't worry about it. Only consider that if you do.
RANKINGS:Use rankings in your decision, but do not make them a primary consideration. Remember U.S. News is a magazine nothing more and they rank more than law schools.
http://money.usnews.com/money/personal-finance/real-estate/articles/2009/06/08/best-places-to-live-2009 . U.S. News claims Albuquerque New Mexico is the best place to live should you move there? I will admit I am little more interested in the town than I was, but I am not loading up a U-Haul for New Mexico anytime soon. The same logic should apply to your law school decision sure look at the magazine and consider it, but don't make a LIFE-ALTERING-DECISION on a for-profit, unregulated, magazine opinion.
CONCLUSION: Again remember no anonymous internet poster myself included can possibly know what is best for YOU. Neither can U.S. News, the National Jurist, Above-the Law, or any other source. The school you choose will impact a minimum of three years of YOUR life, 100,000 or more of YOUR money, and YOUR legal career. Use your personal experience, listen to people that know YOU, and here is a little humor as to why you should not take anonymous opinions to seriously.
