ibooks/3g???

Loving the new 3g. So i bought a few books on the ipad which i guess is the only way to buy them. But how do you back them up on your computer and where is the folder? I can't find it. Also, if you then delete a book on the ipad but want to read it later how do you copy it back. I deleted a book on my ipad that I purchased to test it but now I don't know how to get it back. Thanks

I went into the books tab (I mannually sync) thinking I needed to toggle that but when I tried to check the book sync box it said it would erase all my music and video?
