The rule of thumb I always see referenced is 123. One week in primary, two weeks in secondary, three weeks in the bottle.
Of course, getting two identical FGs three days apart is still required before bottling.
Check out Wirlfloc tabs also. I am a brand new brewer, but they seem to work like a charm. Directions say one tab at 15 minutes, but on advice from this board I used a half a tab.
