Advice needed

Some background on myself. I am 24 and currently work in a large ICU where I have been working for about 3 months now. I previously was a med surg nurse but got tired of that setting. I decided about a year ago I wanted to be a CRNA. I'm currently working on my bachelors and should be done in February of next year. Unfortunatley my undergrad GPA prior to my bachelors is quite bad. I went to engineering school out of highschool with no desire to be an engineer and then after a year wandered about the academic sceen until deciding to be a nurse (which I love by the way). I wasn't motivated in school and my undergrad GPA is about a 3.0 with mostly C's in my sciences. My bachelors program however I'm holding a 4.0 and plan to graduate with it.
So here is my question, I want to be a CRNA and will do whatever it takes. So what will it take? Can you guys tell me what certifications I need to go after? What extra classes to take? I know that I need to do some graduate science to show that I can handle it and I need my CCRN but what else is there I can do? Any help is greatly appreciated.
