RN, Bachelor degree or Associate degree?

I'm not in a nursing program yet. I will apply next year though.
My goal is to become CRNA..I know I need at least one year of nursing experience in ICU. Does it matter if I have a bachelor in sociology when I apply?
By the way, I graduated with a bachelor in sociology. Now I'm going back to school to get my AA/BS in nursing..

2 questions:

1. Will most CRNA schools accept my sociology bachelor?

2. Should I apply to AA program to get my RN license? or BS program? Which will make me a competitive candidate for CRNA programs in the future?
