There is nothing else you can do. Get the LSAT up. After that make sure your app materials are flawless. There is a good book on law school personal statements and such by Anna Ivey. Your local library might have it or you can buy a used copy off Amazon marketplace. But don't worry about that right now, just focus on the LSAT. There is an LSAT section on this site that will give you all kinds of advice on studying.
Thank you for recommending the book by Anna Ivey. It's very helpful.
