Oh dear...
Recovering the deleted files can be a bit difficult. I guess you can try Norton. For future referrences, I suggest (strongly) you don't use the Library window to delete your files. When you delete files there, they don't even stay in the trash can. They just vanish. You go to Tools>Optons>Sharing and highlight the folders which you don't want to share, and click "Remove".
BTW, I'm on LW 2.1, but I don't think there's much difference from what you're using.
Good luck, my friend.
