I'd suggest checking out this thread:

It has links to the application results at most of the top schools for GMATclub members this year.
Stanford and MIT are among the toughest programs in the nation to get into. Your GMAT score will about average for admitted applicants (below average for Stanford actually). You didn't give your GPA, but VT is not considered a brand name school so a 3.5+ will put you in range (below average for Stanford again).
Stanford highly values community service and extracurricular activities. If you have had leadership roles in name-brand service organizations, I would say you might have a shot. If not, chances would be almost non-existent. Leadership and teamwork in a work setting are important as well.
MIT will be marginally easier - I didn't apply there so I don't have any details. The other question is, if you just got your MS in 2006, why now do you need an MBA?
Other schools strong in your areas of interest would be Darden, Duke, Haas & Michigan.
