Lenses for a newbie - eviltoast

Hello everybody. I’m planning to get my first camera body and lenses but I’m not quite sure on what lensens to get. I think I’ll get a LUMIX DMC-GF1 which I can find for fairly cheap prices so I can spend most of the money for some good lenses.

What lenses would you recommend me buying? Is there some kind of “general lenses” I can use without having to switch them according to situations? I’m very new and confused by all the technical terms and stuff
