Master's programs are nice and can help your GPA a lot since it is an all new GPA seperate from your undergraduate one. The big thing is do YOU think you can handle it and actually perform well in it? I am in one right now and applying with the same AA on the DAT as you! It is something that is discussed in the interview but they might delay any sort of progress on your application until final grades for the first semester come in (may wait to interview or accept).
Performing well in graduate coursework (which is supposed to be harder than undergraduate) will reflect well but doing poorly will essentially put you deeper into the hole. Also if you can, apply early for one so you have good choices of classes! You can use that time to tailor your schedule instead of just taking whatever is open. You can use that and say "I picked each of these classes for x,y, and z reasons."
