HSLD's explanations are nice, and I would get out the Jeppesson explanation, read it a few times, explain it to the wall without looking at the book to make sure you have it. The main thing is to know what it is going to do if you lose oil pressure (low pitch), know the basics of how it works (such as the flyweights, springs, oil path, etc.) and what the aerodynamic advantages are to having one (pitch matched to airspeed mainly) and some disadvantages as well such as higher drag idling in the flare, higher nose weight, higher mx cost, oil leakage, and slightly reduced glide ratio come to mind. I think it would be good to know why we cycle the prop during a run-up also.
