I went to Dartmouth undergrad and I am finishing my MBA at Babson in 6 weeks. The only things missing from your list are superior GMATs and about 4 years of POST-GRADUATE work experience. Business schools, especially the Ivy's generally don't take students without a decent amount of post-baccalaureate work experience.
(Babson is somewhat of an exception because they also look for individuals who have started their own businesses, the timeline of which is often irrelevant. So, if you managed your own tech consulting firm while in college, chances are Babson will want you.)
To be honest, I was not impressed with the Grad programs from any of the schools you mentioned, including my Alma Mater. They were too focused on "management" and trendy B-school philosphies and were less grounded in *thinking* and being an innovative mind. Yes, I know about Porter's Five Forces and Six Sigma and all that good stuff, but I also think I understand how to work independently in a large organization, something which graduates of the Ivy's lack.
(Disclaimer: I can say this because very close friends of mine have attended those schools and we debate over this constantly.)
