Open Question: World of Warcraft: Brand New, Got some Questions?

Okay, i'm brand new to this game. I've played Guild Wars for alittle bit and Runescape but I'm about to try 'World of Warcraft'. What should I be for my class and what race is best fit for the class. What class is easiest and level's at a decent rate. I don't feel like finding my corpse to much for any Tips or Hints for the game. What makes money, just some general Information Thanks (: Anything Will Help - I Mean anything.
