When you install shingles over an old layer of shingles do you have to put down felt or do you put the new layer of shingles directly over the old layer?
With composition shingles, no felt is necessary between shingle layers. When the exposure of the shingles is the same as the old exposure, the bottom edge of the old shingles is used as a guide for the upper edge of the new shingles in placement. This ability to place the shingles would be lost if covered with felt.

Can shingles be applied directly over existing roof?
sure, as long as the old roof is still flat and not wavy or cupped and doesn't already have 4 or 5 layers of shingles on it. I've seen a lot of roofs with a couple of layers of shingles on them having no problems. Your local roofing contractor will say "hell no" because he'll want to do a tear-off and reroof and make a bit more money. If you can afford it, that is probably the best way to go, but if you want to save some bucks roof right over the old. It's common practice and should serve you well
