Basically I need to know how I should go about removing my old black cloth styled ones (so they are in a good condition to sell to anyone who needs them) and what I need to do to put on the new leather ones.

I don't think that you can remove the inserts. I'm pretty sure you have to do one of two things: 1) Get new door panels with the leather already there. 2) Use adhesive spray and put the leather on top of the existing insert

 

on my leather, if you are talking about that middle piece above the armrest. Just take the door panel off and look behind it. take some needle nose pliers and bend the small little things that hold it on. when there straight just pull out the little piece.

then put your new one in and bend those pieces in the back to keep it held on tight. then put door panel on.

 

leatherseats.com has a tutorial for this.
