Sorry if this is a repost, (new here and haven't done my intro, this seemed a bit more urgent) I found a couple threads about the tensioner, but I didn't see anything on the idler.
As the title states, my idler pulley melted and the belt was destroyed. I went to my local Autozone and bought a new belt and, what I was told, the correct pulley. The one that was originally on the car was plastic (stupid GM thinking that plastic is a good material for anything engine related) and the one I bought was metal.

First question is: Is this the correct pulley?
Second, When I installed the new pulley I tightened the bolt that holds it in place and the pulley then became unmovable except in the counter-clockwise direction but when it does, it slightly loosens the bolt. So, is that normal? If not, what should I do to install it correctly?
