I am also in Bellevue, WA, and I also have a rising 6th grader who is 2e. If you are looking at Bellevue, you should know that the school district seems very opposed to grade skipping - I have heard stories of unwinding skips accomplished in other school districts and making students re-take a grade. That said, they have been very supportive of my children's disabilities, and I've been happy with the education they have received so far. DD will be starting at a "choice" middle school this fall, but I assume that that will not be an option for you, since you are not on the waiting list yet. It seems like people are generally happy with GMSP, although there are definitely some grumblers out there, too.
