I don't know too much about what is required for Stats programs (I'm on the pure math side of things), but it seems like you have a solid background. You've probably covered a lot of linear algebra in your other courses, but this is one class that is often required. I would also recommend you take Real Analysis if possible since this will demonstrate that you are serious about math and understand proof writing. Since you're applying for 2012, is there any way for you to take some courses at a nearby university? It would probably also help to have a math professor write one of your letters. As for where to apply, look for schools which separate their mathematics and applied mathematics departments. It seems like you stand a better chance at schools where your application is looked at by applied mathematicians. Phds.org is a good site for searching for schools but once you have a list, you'll want to run it by a math professor if you can. You'll also want to look into GRE requirements. I don't know whether applied programs typically require the math GRE subject test, but that would be something to consider. If you take it and do well, it could help your application significantly, though it is a difficult test and without a background in algebra/analysis, you might be in trouble. Good luck!
