Daily quests are per account, not per character.
One of the things you get from completing the dailies is 1 Laurel, which is a currency. Of note, you can go to a Laurel vendor and get crafting components by tier. It usually contains 4 different kinds of {totem, scale, fang, claw, venom, blood, bone}, and anywhere from 2 to 6 of each. (I haven't taken good notes, but it's like 6 of something, 2 of two things, and 1 of a fourth.) Darn tootin' useful when you're trying to get over a crafting breakpoint.
