Put this way, it's like a main game with expansion pack. The expansion pack can't run without the main game.

Also, check out the World of Warcraft (http://www.worldofwarcraft.com) website. If you intend to do some regular playing, reading about it is still the best way because it's tiring to answer questions in-game. Do a bit of homework and any questions, just ask.

The website has tons of information but it's not easy to navigate through it since there's so much of it. Plus, it takes awhile to look through everything, especially the FAQ pages. And a lot of things to remember. Besides, if you couldn't find it there, you would have found it further down in the Billing Section. A bit more digging but the information is there.

Possibly also to take it easy when reading posts. It could just be factual but without the intonations from voices, it can sound unintentionally rude. Anyway, prepare for a lifelong journey of having to read up on a lot of things. But if you're prepared to make a lot of noise even if you did feel the insults are justified, you're going to be railroaded in in-game WoW the moment you're rude or flaming back. The WoW LYN posters are tame compared to the other WoW players.

If it's hard to find simple information, it will be harder when you have to push your class hard when raiding or PvPing.

And besides, one day, when you've hang out long enough, you'll get tired of noob questions as well.
