Don't forget the SRD update, too:
Divine Ranks & Powers,
Divine Abilities & Feats, and
Additional Domains, Spells, & Divine Minions (I can understand the damage reduction update, but why-oh-why did they decrease fire resistance of all things?!).
…with that out of the way I think the only thing (that I can recall) that
Deities and Demigods, the FAQ, and the SRD don't cover are the class skills for those Outsider HD; so I effectively house-ruled that
all skills are considered class skills with regards to the Outsider HD—class skills pertaining to regular classes otherwise work the same way.
I'm also pretty sure that the idea that St. Cuthbert once walked the world as a man is a nod to the real
St. Cuthbert of Northumbria, but at least with regards to
WORLD OF GREYHAWK® it isn't necessarily fact (as opposed to Heracles or Imhotep).
