Hello junicorn,
It seems as though you've selected some of the "brand name," private-school MFA programs. Are you aware that there are plenty of public universities, some with excellent funding, that have 3-year graphic design programs for those without a formal design background? UWashington and ASU come to mind, as well as Carnegie Mellon and NCSU (I think). Some of these have programs that seem very solid and worth your time and money. Some do not.
Unfortunately, none of us can really tell you what these programs are "like," as we don't know what you want to know. The best advice I can give you is to look through each department's website as throughly as possible--which includes seeing what kind of work students are currently doing, as well as tracking down the sites of alumni and seeing their current work and employment. That's the only way you'll be able to get sort of intuitive feel for what each department is up to. Of course, "lurking" on forums devoted to design and design education, such as this one and Core77, is also a good way to do research.
For instance, I was not impressed with MICA's student work, nor did I find SVA very appetizing. RISD and Yale both seem exceptionally devoted to print and web design, sometimes with experimental media/digital flairs, while CCA and Art Center seem to take more of a holistic approach to design (CCA's program, after all, is simply an MFA in "Design") and attract business-minded folk and architects as well as people who want to make masturbatory booklets, like they do at Yale (you can begin to see my biases here). CalArts has hardly any funding, and seem to be making the most extreme and involved kinds of designs, very complex stuff. Yale seems to be making a lot of theory-driven, deadpan design, and a lot of the student work looks alike, which can be good or bad depending on what you want.
These are all only impressions I've taken away from their websites, programs, and bodies of work, and I'm sure that a lot of my impressions are simplifications or are outright incorrect. You can only know for sure by researching for yourself. If you're unwilling to do so, and instead want people to tell you what each program will give you, perhaps you aren't quite ready to take on the responsibility of a graduate education.
