Agree with the above recommendations with regard to forums. I think I'm on five or six BBQ related forums, but use three regularly for different reasons:
KK Forum (this one) -- to get the most out of your KK, and to keep an eye on what @MacKenzie is up to.
Kamado Guru -- All other things Kamado, which is a LOT.
Amazing RIbs -- There are two parts to this site. Much of the free part has been organized in a book you can buy off Amazon: Meathead
The Free Part:
Technique -- Presented as "science". Based on your first post, you probably want to review this part the most.
Product Reviews and Recommendations -- Kind of like a Consumer Reports for outdoor cooking gear. This is useful, although there is a bit of an anti-Kamado bias (they love the KK, though).
Recipes -- Most are pretty basic, but some are very good (try the Hamburger Buns recipe).
The Pay Part: The Pit -- the online forum for discussion. I don't use this part as much, but CeramicChef (also a member here and at the Guru, although haven't seen him in awhile) posted a Kamado 101 series there that would likely be of great value to you.
