I don't want to burst your bubble, but if you're asking the sort of questions you're asking, I get a sense that you won't be able to pull everything together in time to have a decent shot.

With less than a month to go, if you're still studying for the GMAT - you won't have time to

1.) Develop a bschool profile/strategy i.e. how you will position yourself
2.) Craft your essays and have them reviewed by friends (several edits here)
3.) Do your resume properly
3.) Get your letters of recommendations (2 or 3) - will they have the time?? Can they write great things?
4.) The adminy stuff like transcripts are the easiest. They shouldn't take that long. Just turn up to the school and ask for one. Bring some id and cash. However, because it is approaching the holiday period they might not be as quick.

Save yourself the stress and money (application fees) and apply next year.
