I think you got it, and Keith had some good suggestions. There is no one single way to do this as far as switches, lights, etc... The other stuff is pretty much going to be the same except for the 110v or 220v options.
If you decide to make that 110v outlet hot 100% of the time, just move the hot lead feed to the other side of the switch. The connection can be made anywhere on that side of the switch, as it's all electrically the same. It might not be a bad idea as my outlet on my deck was also wired as part of one of the garage circuits. I've overloaded it a couple of times and ended up running a dedicated 20amp 110v outlet from the panel in the basement. If you decide to go that route, you might also consider a 20amp inline push to reset breaker and 12 gauge wiring to the outlet (make sure it's a 20amp outlet as they also come in 15amp versions and the outlet, wire and breaker that protects that part of the circuit all need to be rated for 20amps).
