My take, assuming you come from a common demogaphic for IT (asian, indian, white...male, dont listen if you are an underrepresented minority and female). No offense but Sloan and Stanford are going to be nearly impossible, unless you have done something amazing outside of work. You fall well below their avg gmat and are even below their 80% gmat range. Your GPA is excellent but your work experience is going to be common to these schools, and you would need to improve your gmat to have even a chance. Also sloan only has two rounds and the second round is supposedly much harder than the first (less than 20% acceptance).
Tepper, has been climbing the GMAT score range too, its more doable but once again your industry is a huge feeder to Tepper...their class is close to 80% engineers and IT people.
Babson is doable, but why the 1 year vs the two year. Your score is right around their median so its not as big a hurdle as at tepper and they aren't as big with IT people so less competition from people with similar backgrounds.
If it would be possible for you to increase your gmat in a month to close to 700, then seriously consider that. That would still leave you close to 6 weeks to get out applications to schools, which is definitely doable especially if you take some vacation and really work hard on them.
Post what you posted here in the accepted forum, but with more detail about extra curriculars, details about your work, and your career goals...they can give you alist of schools they think are doable.
