As for the actual mechanics of the world going around it must have something to do with the the intial big bang exposion imparting momentum to all of the particles in the universe. At that point the started to collect due to the unexpainable force of gravity (it is very weak compared to the other forces but has the greatest "reach"). At that point the larger collections of matter started to interact with each other and the various planets developed orbits due to the gavitational forces counteracting the momentum of the planets. These orbits gradually altered as the planets swept up most of the debris in space and enlarged at the same time. So the actual rotation of the earth about its axis is most likely a closely balanced deal based on the size of the sun and the interaction of neighboring planets. So should anything change we may have issues. Get rid of Jupiter or saturn and I would no doubt that we may get sucked closer to the sun, and then everything dies. So no blowing up any planets, no matter how pissed they make you.
I can also imaging the moon affects the rotation of the earth, as it does cause the tides due to its gavitational effects on the earth. And all that water moving around will be altering the rotation of the earth somehow.
