This may sound dumb. but...if I upgrade from 8.10 to 9.04 will I lose all of my emails, addresses, bookmarks, etc????

First of all, if you don't know and don't ask, that's dumb.
Second: It never hurts to backup.
Third: The answer to your question is no. Your documents and settings should remain intact.
