OK....

Monk has Know:Religion + Spelcraft.
Warlock has all.
OK, i figured out it's the Illumian that's killing you.. I'm used to the human bonus skill, but I'll give it a shot anyways:
Got it. I switched your Warlock and monk levels. You loose 1 hp. (first HD drops from d8 to d6)
Needs 14 int.
LVL1 : Warlock(16 points) - 4 Bluff, 4 Know:Arcana&Planes, 2 Know:Religion, 2 Spellcraft
