1: You're supposed to break in the engine in the city anyways, so the AFM won't have much of a chance to turn on. So, no. I can't see any effect it will have on breaking in your engine.

2: When AFM activates, the valvetrain to 4 cylinders (2 on each side to maintain balance...I think) closes and stops working, the spark stops, and the fuel is cut-off. But the piston keeps moving inside. So wear will generally stay the same as a normal engine.
