I am just gonna respond to most of the things that were brought up, and I thank everyone for the insight into this process:
I really only took one math class, and it was basic in that. I took Elementary Statistics, and a case (a very weak case) could be made for Microeconomics, but that is a long stretch at that.
When I looked at the schools that I applied to, WashU clearly stands out as the top school, but it is not my top school. I really am intrigued by Oklahoma, and their combined GRE range for acceptance is 300 - 315 (which isn't high, but I have a combined 310 so I am clearly in that range).
I do have excellent research skills and I think that is shown in the fact that I have 3 original research papers being presented at pretty prestigious conferences in my region. People from all over the country come to these conferences at present research. Very select few undergraduates present at these conferences.
I forgot to mention in the original post that I also have two published articles in SAGE Encyclopedias with another in the editing process as we speak. That may not mean much, but it is published.
I did only apply to four schools because when I was speaking to my advisor at my school, he told that the more schools that you apply to, schools don't necessarily view you as a hot commodity. He has been sending students to grad school for the past 20 years and found that this is an important tactic in the process. It is also important I guess to note that my advisor has extremely strong connections with the department chairs at both Oklahoma and LSU, but that will only go so far.
Once again, I thank everyone for the replies and the insight into this quite stressful process, and look forward to hearing back from these schools.
