Hi Justin,
No single factor is likely to disqualify you from Ross, and I mentioned how to address your quant score in your other post. If Ross is your top-choice then I recommend getting to know the school and its students/alumni as well as you can. This will help you write strong essays and demonstrate enthusiasm, which can help you balance out your GMAT weakness as well.
On an academic basis I think you should be competitive at the other schools you list.
Best of luck,
Daniel Richards
