Your list is good. I would also add Yale to your list. They are very strong in the non-profit, and are good in the other areas that you mention, too. I know some Yale grads, and they have good things to say about the program.
Also, I can tell you from experience that there's always a relatively small but very dedicated group up social-enterpreneurship-type students at Kellogg every year.
