If it's bisqueware, you can usually take a sharp nail or screw and gently dig out a small starter hole, which will help keep the bit from skittering all over the surface. Bisque has a matte surface anyway, so it's easier to drill that fully fired/glazed ceramics. Give yourself plenty of elbow room, then set the point of the bit in the starter hole, at an angle of maybe 30 degrees off the surface. Start the drill as slowly as possible, and raise the drill as it begins to bite into the ceramic, until it's perpendicular to the surface. Once the drill is well-settled in the hole, speed it up a bit. Be patient, don't press down hard on the drill but allow it to grind out the material.
However, I agree with Laurie--there's not much point in drilling holes until you know you need them. You've also got to remember that there's got to be a good airflow around those holes, so if you drill through the bottom of the piece it will need to be elevated to work.
Ooops...sorry, Brock, didn't see your post. Yeah. What he said.
