Door Glass adjustment

Getting ready to install my sport mirrors so was lubeing up my window regulator and ended up with a few questions.

1. There is a bolt with a slot and a lock nut on it which from my playign seems like a stop of sorts. How do you correctly set this? My window rolls all the way up then requires an additional crank of the handle to seal it its not a nice firm stop.

2. The rubber bumpers at the upper front that keep the window from rattleing have worn out in my car, who makes these?
