Flight controls should be along the lines of the 777 only 'more modern' what ever that means really.... probably a couple of hydraulic systems at least but with better plumbing?!
The variable trailing edge business I think is being operated via electrics to the flaps on the AA 777 testbed however not so sure about on the real deal.
It says here that you can run 400 homes from the 1.45MW a 787 kicks out in electrical power so I guess anything that can be electrified will be.
Interesting about those brakes, also heard about this 'brake to vacate' thing where you select your runway exit and provided you put the machine down in a sensible place it'll slow you as required to leave at the chosen exit, life gets a little easier...
