2) How good is MM2? Arcane Power?
MM2: Good, but still using shaky monster math. The MM3 is, quite frankly, far better by the numbers; however, the MM2 has some awesome classic monsters in it, so... eh.
As far as monster resources go, Open Grave is smashing (but again, with early-edition math; this is a common but easily fixed problem); I use both MM2 and MM3 a fair amount; Demonomicon is pretty cool, though specific, and uses the revised math; Monster Vault is can't-go-wrong good; MV2 is cool, but pretty much low level only and full of very flavorful but campaign-specific villains that are easily reskinned or reflavored.
3) Is there a Wis/Cha race?
Deva is Wis and Int or Cha, and kalashtar is Cha and Int or Wis.
