Go to **broken link removed** and get some 18 or 22 pF capacitors from him. He's got good prices and low shipping. If you can find them in a store locally, that would be great. Radio shack doesn't carry them for some reason.
Anyway, pretty much you just connect each of the oscillator pins to one of the capacitors, and connect the other ends of the capacitors to ground. You don't really need to worry about the value of the capacitors.
Unless you are making a program that is really really really time sensitive, and you notice an unacceptable drift, just go ahead and stick in either some 18's or 22's. Whatever ones you go with, just make them match. Don't worry about calculating anything either. Works for me. 8)
