World of Warcraft Attributes?

I would like to know a few things about the hunter. I have a Blood Elf Hunter that's specialized in both Marksmanship and Beast Mastery. I want to know the attributes that is best for a hunter (ex. Haste, Strength, Agility, Intellect...). I would also like to know what "order" I should learn them in. Also I'd like to know the same thing for a Blood Elf Death Knight (Blood and Unholy) and a Night Elf Druid (Feral Cat and Balance). Thanks! :) Either a link to a guide or something or an answer works!
