The chest and back are opposing muscle groups. Basically, working one does not effect the other. In a classic superset, one exercises opposite muscles in a back-to-back fashion, with no rest in between. The best example of this is doing bench press (chest / pecs) and rows (back).
The table below shows that both incline bench presses and flat bench chest presses work an. Also, because of the angle of the bench, this exercise puts less stress on your rotator. Do 12 repetitions and then place the bar back on the rack.
The bench uses your shoulders, triceps, forearms, lats, and pecs, traps, rhomboids, and pretty much every muscle in your upper body. However, the bench press doesn't JUST use your upper body. When you bench properly, you use your lower back, hips, and legs as well.
