To be honest, you may want to cut down on that list and add other schools where you'll be more competitive.
As a Big-4 audit guy, you're going to have a tough time at the top 8 schools:
HBS: long shot. You're up against too many bluer chip candidates (who have enough trouble getting in themselves). Also, they really like high GPAs (and while you have an explanation for your undergrad, you don't really have an excuse for your masters GPA which is basically the same, even if you said you were working full-time; too many "explanations" so to speak ).
Columbia, Sloan, Booth, Kellogg: stretches. You have an outside shot at these schools so it's worth at least applying to 2 of them. But you should look at other schools as well to better your odds.
Duke (and peer schools like Ross, Darden, Cornell, UCLA, Yale, NYU): these are sweet spots for you and where you'll likely have more luck. Focus on 3-4 from this list.
