To jpin22-
First, I have no inside information on your admissions prospects. I'll be rooting for you! In the case of such an extreme split in your LSAT scores, it is helpful for an addendum of explanation (assuming you have a good one, as opposed to hangover or test prep) that doesn't come off as whining. Assuming yours is decent, they'll focus on the higher (more recent) LSAT, which should give you a good shot- the only problem is that they are also concerned about what they have to report to USN&WR, which is (I believe) the average. I think your odds are good, but other than that, I have no info. Other stuff:
1. Generally- you don't mention this, but if you are not in-state already, begin getting your ducks in a row to get in-state! Driver's license, voter's reg, etc.
2. Living? Apartments cost $600 -$1000 for a one bedroom (depending on luxury and washer/dryer). For a two bedroom, a little over $1000 (split with a roommate). Houses right next to law school are expensive (~$2000 for three people) - see Steve at Wilberts, less so farther away. These prices are going down (two months free rent, etc. offers). As for where? Depends. There are places close to Law School, and places farther away. Gainesville has tons of places for rent.
3. Do whatever you'd like over the summer. There's a book, Getting to Maybe, that some people say helps get them to understand the "frame of mind" to take their 1L legal exams. But mainly I'd relax or earn some $. They'll teach you what you need to learn.
4. Pizza places? It's a college town. Sushi places? Quite a few. I love sushi. There's the high-end restaurant (Dragonfly). There's the quick stop (Rolls n Bowls). There's Bento (Box and Cafe). There's delivery (Sushi 2 Go). There's a bunch of other places. Some of them are good. None of them are NYC/LA quality, but they're okay.
5. 1L grades are the most important grades you receive. This is for many reasons-
a) because they're the only things you have when you apply for a 2L position,
b) because they're the only time you're taking the exact same courses as your peers and therefore they serve as the only true benchmark and,
c) because they help determine if you get on to LR or other journals automatically (as opposed to writing on).
They've mucked up the class schedules depending on profs' availability recently, but the typical schedule is 16 CR in the fall, 14 CR in the spring with the following:
FALL:
Contracts
Torts
CrimLaw
Professional Responsibility
Legal Research & Writing
SPRING:
Constitutional Law
Civil Procedure
Property
Appellate Advocacy
You will take all of these courses first year; they may switch some of them around (example- take ConLaw first semester and Contracts second).
Good luck!
