As a graduate of a top-ten school, I do have one piece of advice in choosing a school. If you know FOR CERTAIN the market in which you want to practice after law school, choose the best school IN THAT MARKET that you get into, even if you get into "better" schools in other markets.
To illustrate, I am from Los Angeles, and I knew 100 percent that I was going to return to Los Angeles to practice no matter where I went to school. Not having received this stellar advice I am offering here, I went to law school in Chicago. Now, I loved my law school, but certain things hold true that I didn't really consider:
1. Interviewing for a job in Los Angeles is much more difficult if you live in Chicago. All my law school friends who were interviewing in Chicago could schedule callbacks at any time (even on a morning of a day they had afternoon classes). I had to fly to the West Coast every Wednesday night, interview all day Thursday and Friday, and fly back. Exhausting, irritating, bad for school AND interviewing, and kinda pointless. If I had gone to school in LA, my interviewing would have been far easier.
2. Most school, even those with national reputations, open doors more easily in their home market than elsewhere. I work at a firm where the VAST majority of attorneys went to UCLA or USC . . . or Loyola (Los Angeles). The same is true in Chicago firms---they have a huge preponderance of Chicago and Northwestern grads, as well as John Marshall and Loyola (Chicago) grads. A degree from a Chicago school (even a top-ranked one) just doesn't open the doors in LA that a degree from a "lesser" LA school would. And the same holds true for someone trying to get a job in Chicago with a UCLA or USC degree. You're still going to get a good job, of course. But it will be much more trying, and you won't get the same range of offers.
3. If you go to school where you intend to work after graduation, you will have a much easier time summering at a local firm. I had to move from Chicago to LA twice---once for my summer, and once after graduation. If I had gone to school in LA, summering would have been easy.
4. If you summer after 1L and/or 2L, and you go to school in the same market, you may have the opportunity to work at your firm during 3L. A summer colleague of mine who went to USC worked 10-12 hours per week (at a pretty nice wage) during 3L simply because she was already in LA, where our firm is. She earned money, and, more importantly, got lots of experience that I had to wait until after the bar to get. I could have worked during 3L as well, but I was in Chicago.
5. Some of the best friends you are ever going to have will be from law school. About half my law school friends stayed in Chicago, and the rest went to DC, NY, etc. Not one came to LA. I wouldn't trade these friends for the world, but if I had gone to school (even a "lesser") school in LA, I would have made some really good friends who would have probably been in the same city after graduation.
Just my thoughts, but something to consider as you are choosing schools. Don't get too caught up in the rankings. Use some common sense.
