Window stop adjustment

Is the window regulator stop adjustor the slotted bolt w/locknut next to the crank? The illustration in the manual is unclear to me. My window stops about 3/4" below the top of the door.
Also, the slotted adjustment below that appears to adjust a bracket that rests against the window when it's down. The bracket looks like it should have a rubber bumper of some sort, 2nd pic. Are the rubber pieces available?
