For the warlock question, I made a half-elf warlock with staggering note.
Staggering note, for purposes of this question, does charisma modifier damage.
This warlock has a number of bonuses that he can add to his damage.
His PP notes: "… and a bonus equal to your Con mod to damage from lightning or thunder powers"
He also has a quickbeam staff which provides energized (thunder) which "you gain a +3 bonus to damage rolls if a power matches the implement's damage type"
Staggering note provides thunder keyed damage.
How much damage is done on a successful hit by this warlock?
