With your vast work experience, US work, and very nice GMAT you are in very good shape for the two schools you are looking at. Of course, the best way to increase your chances for scholarship/fellowship/etc. is apply to as many schools as you ca.
Looking at your goals, and what sort of program you seem to be going for I'd suggest having a look at: Madison, Mays, Arizona State, Marshall
(though to be honest, there are plenty of other excellent choices out there)
Hope this helps you get your list kicked off.
