Those are all great schools to choose from, Branson. I am not sure how specific you want your career to be (i.e. general mgmt consulting anywhere VS social responsibility on the west coast), but if your career goals are not toooooo specific, I would go with Ross and a full ride. I mean we're talking about a full ride here!!!! All three are great schools, and I don't think one or the other is going to make or break your career (unless you have a specialization in mind that one schools dominates). In the end, whichever school you go to, you will be working alongside MBA's from Haas, Ross, and Tuck...wouldn't it be nice to be doing so debt-free?
There are first-years on the forum who have been in your situation, and they have chosen the lower ranked top-15 school and a full ride over the higher-ranked top-15 and less or no scholarship money (yours happen to be ranked high to middle-of-the-pack in the top-15). I know for a fact that they are doing just fine in their internship hunt. Like Kwam was told at GSB admit weekend, when you're in a top-15 school, you're good to go!
Good luck with your decision, it will be a fun one to make, and last but not least...congrats!
EDIT: Of course you have to like the school, culture, fit, students, etc.
