is your strategy to apply to ALL of these schools? if so, i think it will be a LOT of work for you. it's doable, but not without a great deal of pain and sacrifice
my advice is to keep your bands of schools, but select only 4 or 5 of them in total.
also, i don't look at UCLA and Michigan as separate bands. I'd say they are both equivalent in terms of exclusivity and difficulty being admitted.
i cannot comment on your chances without more info, such as your UGPA and the reasons you want to attend (career goals). as for your gmat, i wrote this article that might be helpful to you: http://www.thefirstread.com/should-i-retake-the-gmat/
hope that's helpful,
