Make sure you really bust your butt for the best grades you can get. As much as everyone hypes the LSAT, your GPA matters a lot, too. To that end, try to transfer somewhere that grants A+ grades. My undergrad didn't give A+s, even when we deserved them, which puts me at a disadvantage, because LSAC counts A+ as a 4.333
Also, order application materials from law schools, and take a look at what kinds of things they ask you for on the applications. The fear of having to leave some of these questions blank may spur you to go out and do some new things.
Also, you should start working on your PS before you start full-time LSAT prep--too many people do the PS after the LSAT, and they end up getting their apps in late (i.e. me).
Good luck with everything!
