lol ok ok
right first things first you need to think about what you want to do in the game,
do you want to be the main fighter? do you want to have a pet? do you want to deal damage via magic, would you like to have a character which can morpg into animals and so on.
From there plan out your character. Do you want to be a Alliance or horde toon? human or gnome an so forth.
Types i find fun are orc hunters, troll rogues and such. I am not into the magic side of things.
All toons have their pro's and con's some quests will need you to group up others wont. In some cases ie hunter, you wont need to team up at all.
A hunter with pet can be a deadly combo. (you would never guess i play a hunter
)
I suggest you get yourself into a n00b guild, its there that the game gets good you get to quest with regular players and get to know what their like and such, also makes the game more fun.
As said by other wow is also about the social side of things, which really makes the game cool.
