The gravity of the moons helps to give the rings their distinctive shape. Some of the moons, due to volcanic activity and gravitational friction from Saturn, spew out tons of material into space that then adds ice and/or methane to the rings.
Beyond that, some moons around ringed planets actually "shepard" the debris rings to maintain the ring-like structure. The two Saturn moons Prometheus and Pandora are so called "shepard moons" that maintain Saturn's faint "F" ring.

Over 60 moons have been discovered orbiting Saturn so far, but many of them are tiny moonlets imbedded in Saturn's rings, and are only a few tens of miles across. There could be as many as hundreds of undiscovered moons hiding in the rings.
Neptune has 13 known moons and a ring system with 5 principal rings, which were discovered in 1989 by the Voyager 2 space probe. (see related question)
Not sure there is anything: all the outer planets have rings, the two gas giants have many moons etc.
