Current theory states that the moon was formed when a Mars-size object hit a proto-Earth about 4 billion years ago, emitting a large amount of debris that eventually collected to form the moon.
Rocks on the surface, and dust, have resulted from millions of years of bombardment; shattering of it's original surface and melting of materials to form the current surface.

I don't think our knowledge of how the solar system formed is good enough to say that the answer to your question is obvious. But some of it has to do with the gravitational influence of other bodies. The formation of large planets such as Jupiter makes it harder for other planets to form, because the small rocks are now more influenced by the gravitational force of these other planets than by each other. Saturn's rings may be a different case from the others because modeling suggests they are much younger than the planets. The rings are thought to have formed from the debris of moons that broke up from collisions or from being pulled apart by Saturn's gravity. For the most part, the gravitational influence of Saturn and its moons will prevent the rings from clumping together, but there may be places within the rings where the moons' gravity causes clumping, and perhaps another moon will be formed. There are some fair-sized Kuiper Belt objects (e.g. Pluto, Sedna, and Eris, if it can be considered as belonging to the Belt). We don't have a clue what's going on in the Oort cloud. Its existence is mainly conjecture at this point. Some of what we don't know about the outer solar system is whether the objects formed out there, or formed closer in and were later forced into more distant orbits.

Well the moon itself was formed from the compression of floating particles, and the rocks on the moon are parts of it that have broken apart by some process (such as being hit by asteroids).

By falling rocks.

Initially by the accretion of dust under gravitational force, and later by the impact of countless rocky bodies.
