Don't bother retaking the GMAT. You'll be fine. Adcoms don't really care about the AWA all that much, because it's essentially graded by a bunch of hourly workers (college kids and other part-time folks) based on a cookie cutter formula. Adcoms never really knew what to do with the score, so they basically ignored it.
In any case, you should be in range for the EMBA/part-time programs on your list. Just do the best you can on the applications and you should be competitive. Good luck
