Interior question (pics)

I just purchased a roll of black car carpet from an auto parts store. I did the whole cargo area with it. Mine had faded to brown from the sunlight since this area receives the most sunlight. It was easy to do. I just used the old pieces to trace on the new carpet. It cost me around 50$.

Oh, and yes, the plywood piece is carpeted like Adam said. There should be black trim pieces on the outer edges of the plywood.

Dang it ...no outer trim on the edges of plywood.

Questions:

1 What do the outer trim pieces look like? I mean is there something that they remind you of that I can buy now days to put around the plywood?

2 Does the carpet roll up on the plywood from the cargo area or is the cargo area and the plywood two separate carpet pieces? (I hope you understand that question)

3 I've noticed that there is a chrome strip with screws on the cargo floor up front toward the fold down seat. Does the carpet need to go under it and then the chrome strip screwed down?

4 Where does the carpet need to end on both sides (left and Right) of the cargo floor ? Underneath the side panels I'm guessing.

I know that's a lot of questions (LOL) but I've got to ask them if I want my car to original as much as possible on the interior.
