Definitely go for some advanced writing courses and some more math wouldn't hurt either. Lawyers have to balance a lot of figures, esp. if you're going into entertainment law and you don't want to have to rely on others to crunch the numbers for you. So I recommend math/accounting/business/etc. for that. A lot of law school students I know took at least one course in Latin and claim that helped a lot. Also, do you have a minor? My sister told me that I needed one because, when she applied for grad schools, they implied that her taking a bunch of sporadic classes when she could've chosen a minor made her look lazy compared to the other applicants. So, when my psych major left me with a lot of "filler" classes to take and I used that space for a minor and it made my transcript a tad more impressive.
Did you try the Academics thread?:
