Need help finding parts: door "rail?" and rear tray fabric



Our 2009 CLK550 coupe is in need of some love. In the rear seat, there is a tray in the middle with a fabric insert; ours is stained pretty bad (those darn kids!!!). Anyone aware if these can be replaced? Part #? or how to find a part #?
Also, when wiping down the drivers door; i noticed underneath the door there is a long black plastic trim piece (running the length of the door) that is missing... i cannot for the life of me find this either and appreciate any help finding a part #.
Many thanks!
Driver's side, missing
Passenger side, this is what i'm looking for
Those darn kids!!!






Great idea wrapping the fabric in leather; i like that and bet it looks nice. I've tried all my "go to" cleaners and even steam which did the best job but still it is 11yrs old and went through two messy kids back there.
