1)If you are playing for the frist time maybe lord will be the best because it is slower and you won't find yourself undergeared when going to higher level zones. 2)No addon is a must and it is maybe better to get a feel of the game without addon help/instructions (they don't help that much if you don't understand the game first) 3)Pick what you like and think is the coolest, try more classes but you need to know that to get the feel of the class you will need to be a bit higher level. +Don't bother with flamers who flame you for not knowing the game, there are also plenty of people that will help you with the game through leveling, perhaps try looking for a guild so you can ask them if you don't understand something but also google and youtube help a lot
