Thanks for your post. In regards to the GMAT, for the programs you are applying to we would recommend you take the GMAT again. One thing that is important to remember is that in your business school application, your highest GMAT score is self-reported. For this reason, admissions teams focus on your best score, and there isn't any harm in taking the test again.
If you'd like, we provide free GMAT advice here: http://www.stacyblackman.com/test-prep-hub/
We also provide free 30 minute phone consultations here: http://www.stacyblackman.com/contact/
