Misha. Do the AA. All the AA's I talked to love it and don't regret how much effort it took to get there. You sound like you know what you want but you're searching for an approval. You don't need a 3.8 GPA or 30 on the MCAT, trust me. When you finish going back to school (and you will, right?!) your resume and personal statement will be taken into great consideration. Don't get a nursing degree and decide to switch, this shows a lack of comittment and loyalty to not only yourself but to the health professions (in my opinion). AA all the way!
