Look here for info on the quest:
Simon is by General Judd in the back section of TC on the left.
Since it's your first time in...
-Take 1 scroll and the rest speed arrows. Don't go if you can't use speed arrows.
-Don't let your fly timer run out when you're among the mobs, and you won't need pots.
-Don't lure the mobs to the other archers, and they won't mind you being there.
Ask a friend to show you the best spawn for archers. And if you need to leave to level gear, you can probably trade arrows to others for diamonds or something.
