That looks alright!
For the U-brake, I had one chainstay mounted and it eventually snaped at the boss join. I think you will be fine as there is a brake booster fitted. BTW the boss position of a U-brake relative to the wheels are not the same as cantis.
I would have reservations about the hub technology, and would favour a Shimano cassette and freehub - something 7 speed like XT M730 or M732 or the slightly lower grade DX version with the steel axle rather than Cro Mo. You could then pack a few sprockets if need be.
STX is not bad kit either., but invest in either Surly steel or Blackspire DH / TA / Middleburn chainrings on it instead.
Agree with you about the thumbies.
