150 days should be plenty, Human's just spouting blasphemy.
Can't think of any decent tips off the top of my head, though if you run into trouble in specific areas I might be able to help. Well, here's a tip, survival and gambling are both mostly worthless skills, and if you want a powergaming Fallout build then you'll want gifted. SPECIAL stats are much more important in Fallout 1 and 2 than 3 or NV, dropping some initial skillpoints for higher SPECIAL across the board is well worth it, especially if you invest some of that bonus into intelligence, which pays off with more skillpoints per level than in FO3.
