Go for it! Apply now to your top choice schools. As far as how many schools, just remember chances are you will get interviews to all of these schools, and will pay for the travel expenses, so if there is a school that you do not think you would attend if accepted, don't apply. On the other hand, if there are three or four schools you would consider seriously attending if chosen, go to the interviews and don't make a final decision until you have seen all schools and felt out all the programs. You are very competitive, more then you think! I also thought I was up against all 4.0, top trauma hospital, 5 years plus experience, brilliant candidates, and some were, but not all, and with my stats that are even less competitive then yours, I was accepted into all the schools that I applied! You are extremely competitive with the GPA, prior experience with CRNA, level one trauma ICU, and committee work- go get em!
