Rear Trunk Trim

[lkv0315]

It has been like 2 months since I took everything out of the trunk of my car, like all the trim that holds the tire chocks, towhook, etc. and due to negligence on my part I forgot how to put it back. Starting with exhibit A
A)The tire tray: I removed it so that I could run wires around it's mounting points easier. Does it go on top of, or underneath of the jack?
B) The two shorter, rearmost side pieces come with lots of little plastic nuts, black ones and white ones. Which ones go where? Also when I went to put the rearmost driver side piece, it overlaps a loop with the rear driver side piece. Which one of the two goes on top?

P.S. Sorry I post so many threads, I just have a lot of questions
