Roald is correct most law schools have an application deadline in January. So if you want to enroll in Fall 2014 you should submit your application in Fall of 2013. The reality is the earlier you apply the better your chances. Furthermore, many people apply to law school before they have officially graduated from undergrad, which sounds like the position you are in. They will look at it since your GPA is basically set if your in the last semester of undergrad and they will just look to your LSAT.
As for financial aid etc will get taken care of when you start law school and the process was quite easy for me and everyone I went to school with.
One thing worth doing that I did which saved me nearly 1,000 in application fees was going to a LSAC forum go to each schools both write your LSAC number down and many schools will give you a fee-waiver in an e-mail. Or e-mail you prior to the forum telling you to come to their both and they will give you a fee waiver if you have the e-mail. I applied to about 20 schools for free this way and since you have time I recommend doing that. I think it might also help you slightly in admissions as it shows a sincere interest in the school if you stop by their booth.
All you can do now is keep your grades high and do well on the LSAT if you haven't taken it yet. Good luck.
