Advice to Get Into CRNA Program

Hello, I am looking for some advice on how to get into a CRNA program.

My story:  I graduated nursing school from a large state university at a pretty young age and did not at all have the drive I have now to get excellent grades. Overall BSN GPA was 3.4, and science GPA was quite low, about 2.9. I got C's in physiology and organic chem, B- in mircobio, anatomy, and health assessment. 

7 years of rehab/floor/stepdown nursing later, I took an OR position at a level 1 trauma center, and had the epiphany while I was training that I absolutely wanted to go into nurse anesthesia.  So, I left that OR (which was a tough choice but needed to be done), but unfortunately could not just transfer into an ICU at that level 1 trauma center, and so am currently in an ICU at a community teaching hospital, although it is a relatively large one and we do occasionally see balloon pumps, impellas, and swans- But no trauma. 

Still at less than a year of ICU experience, but I've got plenty to keep busy with while working.  I got CCRN certified.  I took the GRE and got a 315, 4.0W.  

Clearly I need to retake science courses.  I retook physiology and got an A, and am taking a 2-semester combined chem/o-chem/biochem sequence and have an A in the first semester, will be taking the second one soon.  

My question is-- What else should I take? What else should I do? I am considering retaking anatomy since I got the B- and possibly microbio.  I was also going to take a biochem course.   I got a B- in health assessment in semester 1 of nursing school so was thinking of taking a grad level health assessment course.   

I will really do whatever I have to do to be accepted and successful as a CRNA, so please just give it to me straight.   Thank you.
