There will be many options depending on what your LSAT score is. Whatever law school you apply to will combine all your undergraduate grades 3.0 and current 3.8 which I imagine would result in a 3.4 approximately which is pretty good. However, you will basically need to get a 150 or higher to get into any ABA school and 50% of LSAT test takers don't do that.
For the time being I would really focus on maintaining your GPA and getting an LSAT score until you have your official GPA and LSAT score there is no point in looking to in-depth at schools, because you really don't know what your options are.
As for the making money impacting your GPA etc when admissions time comes around I don't any admissions committee will give that much credit. People go through a lot during the undergraduate years and some don't is it unfair that some trust fund kid got a 4.0 and didn't have to worry about money sure, but there are also people that dealt with a lot more adversity than having to worry making money while attending college.
When you finally do get your LSAT score I think lawschoolnumbers.com is a good place to see what your options are. Good luck.
