set up for BL revo.

No, that motor does have three wires, the other one is just hidden. All current brushless motors have three main power wires since they are three phase A/C motors.

Yup, that's almost all the electronics you need; don't forget the radio. :)

Obviously, you'll also have to come up with a custom motor mount and a way to mount the batteries and the electronics.

If you onyl get one pinion, I'd get the 14T. I would still get the three different spurs so you have some gearing options.
