You possibly want Noxxic.com
battle.net/wow, which has its own forums
And The existing World of Warcraft thread
in these forums.
And Holmes, Blizzard is giving away the Wrath of the Lich King expansion and free level 80 characters, but only through the Recruit a Friend program.
As for general, get into the game advice...play, really. If you don't understand something, ask a friend. I am sure that you can find someone to ask in the game (but probably not Trade). Most of learning the game comes from experiencing stuff, and once you have a working understanding of the general mechanics, using a resource like Noxxic is quite powerful in learning how to play effectively.
And if you're really having trouble, play a super easy class like a hunter or mage.
On second thought, let's not go to TechReport. Tis a silly place.
