If memory serves from working on display IDs there are still a few things you're missing. As Amaroth mentioned you need to add an entry to the creature_model_info DB. Furthermore, your DBC looks incomplete. The display IDs you used for the armor pieces only tell it which geosets to use. It doesn't, IIRC, define the texture. You do that through column 21, which you haven't defined.
I can't see your link to CreatureDisplayInfoExtra.dbc, which should be in 3rd column. Enter your extra's ID there.
