Im not exactly an authroity on this subject in particular, having only read Revelation once, however, I think you might be interested in reading
Isaiah 14, which is actually the only chapter in the Bible that mentions the name "Lucifer" that I know of.. It talks a little about him being cast out of heaven and so forth. I actually once had a professor in Bible College who thought that 'Lucifer' here referred to Nebuchadnezzar rather than satan though. I always grew up thinking that lucifer referred to satan, but I personally have no clue. I just thought I'd give you the passage as I figured you might find it of interest in your studies on this topic, best of luck =)
