trouble with my paladin
Also, make sure you have Righteous Fury up. It's a massive threat increase which should eliminate most aggro problems. Use Reckoning to taunt mobs back to you if you lose aggro.
Okay now what would I want to look for if my Pally is in the 40's-50's and what rotations would be good?
Gear at that level is going to be the same. It's not really going to change until 80+ when you start seeing more choices in secondary stats.
For rotation, just follow the Prot guide stickied here ( http://us.battle.net/wow/en/forum/topic/7005430614 ), ignoring abilities you don't have yet.
