Here are the pictures and instructions I made some time ago. I sell the carbon fiber vinyl to do this job if anyone wants to tackle the project. You can get it here:

Here's how to remove the existing wood pieces off of the door panels. This how to is only for the 2000-2002 LS's. I don't know how the pieces are attached to the 2003 and up LS's.
Actually taking the existing wud pieces off wasn't that bad. On each door panel the wud strip is held on by 13mm nuts AND there is three plastic studs that are melted onto the door panel. The three plastic studs are easy to Dremel off and really don't add any support to the wood pieces once it's re-intalled. Here's a picture of the back side of the driver side door.
Once you have removed all of the nuts and plastic studs you will have to remove the Memory Seat Switch and the Door Lock Switch to get the complete unit out.
Here's what it should look like once you have taken out the existing wud unit:
To cover the power window piece it's easier to remove the power window unit.
You will only have to remove the Door Lock Switch on the Passenger side. Here is a picture of the inside of the Rear Driver side panel. Note that there is not any washers to take out only the 13mm nuts and the plastic studs. There isn't a lock switch mechanism to take out. It's on the arm rest.
Here's what the existing wud piece looks like once off of the door panel:
Also, remove the power window unit to cover the piece.
