Before you do anything drastic, take a deep breath and step away from your G4!!!
The "desktop" on a Mac is not something that can be reformatted. This action is normally reserved for Hard Drives.
Reformatting a Hard Drive will normally destroy all the data that it contains.
Of course you can save all your mail and bookmarks. Just find them and drag them to another drive or burn them to a CD.
I guess the really important question is, what makes you think that formatting your hard drive is a really good idea?
Please do nothing to your drive until you have answered this post. I would hate to see you destroy everything just because some setting is incorrect somewhere.
