Rogue Leveling Guide
One of the first decisions you may need to decide is Sword or Dagger. My advice is to you as a fellow rogue is to lose the dagger. Your mainhand weapon needs to be a sword/mace. The benefit of using a sword (or mace) as your mainhand weapon is that every hit will result in dealing a large damage to the enemy. When using a sword sinister strikes are twice as powerful, particularly in these early WoW level sinister strikes can be almost as powerful as a backstab attack - whilst limiting the risk of missing which some when using backstab.
When using Swords and Maces you don't really need to be concerned with positioning - just smash with your Sinister Strike. Unfortunately, when you're rogue leveling, good fist weapons are few and far between in the leveling process.
Gearing up a rogue (like most other melee classes during the WoW leveling process) is all focused on maximizing damage whilst leaving just enough stamina for a reasonable health recovery.
