As to the above, I think Sklansky hit the nail on the head:
In loose games, want to stop bluffing and semi-bluffing so much, since they will probably call. You can relax your starting hand requirements and play more drawing hands since you'll know your opponents will pay you off if you hit something.
In tight games, bluffing and semi-bluffing become more important, since your opponents are more likely to fold. Your legitimate hands, however, aren't worth nearly as much since everyone is going to be playing a good hand.
