Using a properly regulated voltage is not enough?
Well, if oscilation frequency is going to change with supply voltage, then what supply voltage is correct? Also, I want to run this at 5V, and that means making it as nearly immune to supply voltage as possible so that I can get a frequency that's at least reasonably close to the calculation.

Temperature changes affect a few things of a transistor which causes frequency changes.
You mean, ambient temperature?...Or internal temperature due to oscillation and current transfer? Ambient is consistent at 21C.
