When using ceramic pots w/o drainage holes, is it neccessary to place rocks on the bottom level for drainage?

Yes, or you can even use Styrofoam peanuts instead of rocks in the bottom of pots. Depending on the pot size, some people also prefer to drop another smaller plastic pot (with drainage holes) inside the ceramic one. This could also sit on top of the rocks. Anything you can do to keep the plant roots from continually sitting in water is a good idea.
