3) Avoid Cold setting the frame. As the last poster shows, cold setting can potentially make the frame unrideable. If it must be cold set, I advise letting a pro mechanic with frame alignment tools do it. Also, some frames can't have it done to them period, which is another reason to let a pro mechanic look at the frame. My Vega has lugged chainstays, and all my research shows that Lugged frames can't be cold set without damaging the lug. Also, keep the change small, 5-6 mm appears to be the limit for most required cold settings.
