Regional schools like UW have little visibility outside their immediate region. For example, some recruiter in Seattle won't have a positive or negative opinion about the University of Nebraska MBA -- it's that they won't have *any* opinion (i.e. neutral). Same thing with UW outside the Pac Northwest - if it matters at all in the jobs you're going for, it's the fact that it's an MBA will be what matters, and the school rep isn't really going to be relevant.
Anyhow, you have to figure it out for yourself whether you're getting an MBA *only* for the "respect" (or brand), or for the education itself.
Moreover, an MBA is just one line item in your resume. A recruiter ultimately wants to know whether you can deliver results.
As for GMAT, I don't know - get close the average for the school as you can (their average should be published on their website).
