Your undergrad gpa and lack of experience are two huge barriers that will prevent you from getting into a program. Perhaps you have done more research than you led on in your first post. However, not trying to sound rude/discouraging at all, but I am guessing you are at least 2 yrs at the minimum of being ready to apply to a program, considering you don't even have ICU experience yet. Also, a year ICU and 3.0 will not get you into a school unless your father is the program director. While your already in those settings, I would get the credentials you can for those floors. Start looking into retaking classes.
Also, do you mind me asking why you want to be a CRNA?
