There isn’t much point in a paper manual for a game like WoW. The real manual is battle.net.
By default, q and e are strafe, w is forward, a and d are turn, s is backwards and x is down.
When I played, the manual was useful for learning about the features of the UI, the controls, and the basic mechanics. I didn’t associate WoW with battle.net, but I see that battle.net has a WoW section with a game guide now.
Might I recommend you read a crafting guide - I always found that if I saved crafting materials as I gathered them it made it easier to skill up - if you have a bunch of stacks of materials you don’t need to go buy them.
