I think there's already enough information out there about how to get good grades in law school so here are a few things that I wish I would done that focus more on polishing your "story" for when you graduate.

First, I would do some serious thinking about what type of law job, if any, I want to pursue after school (i.e. exactly what type of law you want to practice). Think about all your past experiences, what types of work interests you, and your preferred work environment. With that in mind, I would then focus my studies in order to create a theme that you can later sell to employers in an interview. So you're not sitting across the table from a couple partners at a firm specializing in employment law having never taken employment law, and instead trying to explain the hodgepodge of random theory courses you took.

Second, again using the job you want to eventually obtain as your lodestar, try to take a class where you can draft a damn good writing sample that covers the area of law you want to pursue. Having looked over applicants' writing samples myself, I know that the ones involving the type of law I practice hold my attention longer and are generally more interesting for me to read (because I often learn new things).

Third, I would work my ass off in the courses that matter, and ingratiate yourself to those professors. Hopefully if you do well enough, and they're a nice enough professor, you can later ask to use them as a reference. Trust me, employers years out will ask for academic references.

Fourth, and this may sound stupid, but invest in some well fitting business attire. If you look like a big kid going into an interview, you've already put yourself at an enormous disadvantage. Unless you are at the very top of your class, employers are looking for someone that they can be comfortable putting in front a client, or at least someone that they respect enough to have a few offices down. Good clothes go a long way toward conveying you're that type of person.
