Thanks for saying that mammawlin! I'm not very good at walkthrough type things but I'm fairly good helping in other areas. I'd say the treasure is worth it myself. I found 2 dragon armors in those chests. And don't worry about entering his treasure vaults. He doesn't care. He only cares if he finds your hand in his pocket! (well, maybe not if it's a female dwarf!
Sorry I shouldn't have said that....)
