I agree on faucets you are getting cents for hours of work.  Unless you live in a very very bad economy it's not worth it.  You use more electricity then you make in most cases from faucets I think I'm safe to say.

Signature around member level start to pay pretty good.  Just use them and don't abuse them.   I suggest not doing newbie ones and work on post content.  As your content is more important then the little a newbie one brings in.     Look into joining on around member as there is a decent pay jump there.
