Sync Stuck

I don't know if title is explaining my problem well. Sorry for my English.

I wanted to install (?) books to my iPad 3. Before iPad I was using iPod Touch and iPhone (since iPad, I don't really use them :p ) I clicked Sync and chaos has started. It deleted all my apps and started installing my old iPhone/iPod Touch apps. I was freaked out then plug out my iPad.

Now, here is the screenshots:

I can't delete, sync them. I can do nothing with them. I want to get rid of them. And my "Other capacity" increased to 3,2 GB.

What should I do ? I dont want any podtcasts and musics. Just want a few books. I'm a innocent boy who wants a few books.
