There's also a quest in Klamath where you are rewarded with the ability to skin geckos, giving you a little earner.
that's the reward for rescueing the guy trapped in the gecko caves. Oh, and when you are a much higher level you want to go back to that cave.

And in fallout 2 doctor is a MUST. The perks you get from it are just too good to pass up, even for combat.
