Wow... seems like its been quite a while & no one replied to this. I hope this answer is still relevant.
As far as Entrepreneurship goes, one of my friends - who is also an aspiring independent entrepreneur - is going to Babson, and is very pleased with the program so far (which is supposedly the number 1 school for the entrepreneurship niche).
If you want the opportunity to work for Amazon, then U of Washington (Foster) may be another very fitting choice. Entrepreneurship and international business are their well-known strong suits, and the Foster school is located less than 7 miles away from Amazon's global HQ, which makes networking easier. Of course, Amazon isn't the only web-based business in the Greater Seattle area, RealNetworks - the maker of Real Player, is also HQed in Seattle.
