Sounds good. Personally, I would just focus on the GMAT now and research schools later. Regardless of what schools you target, you're going to try for the highest score possible. So to me, picking a school and then figuring out the necessary GMAT sounds like the reverse of what you should do. In my opinion, it should be the other way around. You should go for the gold on the GMAT and then pick the schools (or consider taking the GMAT again if you feel you can score higher.)
In terms of other schools, I don't really know much about healthcare management or healthcare consulting, but I would guess that those universities with med schools would probably have strong healthcare industry presence in the MBA program. I know, for example, that Tuck has something called "The Healthcare Initiative" the goal of which is to produce healthcare management leaders. I would think that Johnson/Cornell, Stanford, Harvard, Ross/Michigan and Darden/UVA also have at least strong class offerings and professors who deal with the healthcare industry or have some sort of joint program with the respective med school.
Also, I'm assuming you mean the Yale Full Time MBA. I'm not sure if you've considered the Yale Executive MBA that is exclusively for those interested in healthcare.
Good luck.
