Re: NOOB ALERT: Questions for starting out..
The dohicky (technical term, I know) right above the front chain ring that switches gears for the front. Bottom part of the seat tube, right above the bottom bracket. That thingamajig is right about where the rear motor mount will clamp to the seat tube so it's possible it will get in your way. If it does, just put the chain on the big ring and remove the derailleur as you won't be shifting anyway. You only need enough gear to get going and then the motor will do the rest.
