Michael,
In most every case, the faster the growth the weaker the tree. Some of these trees that have been bred for fast growth are really just one ice storm or wind storm away from coming down. Something to consider.
The most commonly used Maple hybrid around the upstate is "October Glory".
Also wanted to comment on the plan a bit. I think you would be happier if the pool decking and back porch were integrated. Having to walk through the yard to the pool gets old. Also, I'm assuming that the "walks" from the garage, etc. are little paths of lawn? if so, think about how you're going to maintain things. All those little walks mean that you'll be getting out a push mower , edger, etc. If you plan to do all the cutting from the seat of a riding mower then you might want broader, wider, more sweeping curves for your bedlines. That tends to look a little cleaner and less "cluttered" anyhow.
I'm with SCGargoyle though.....so what do I know.
