I think it will be fine with the heatsinks, especially if you’re only running 16bit and lower stuff. I’ve been running them on my pi2 with little to no issues inside my SnesPi.
Yes the LED will light up on the original board if you configure it how it’s recommended.
As for the Xbox controller adapter, I cannot offer you any advice I’m afraid.
Post up some pictures though dude, I’m very interested. I can’t actually get my gpio adapter to work at the mo so you may be able to help me.
