What are these door parts?

[PaulDash]

Even with the service manual and access to PET, I can't locate the part numbers for a few pieces that I'd like to replace. These are all parts found in the left door (MY99, power windows, power mirrors, no seat memory if all that matters):

This L-shaped cable guide:


There's a metal frame (996.537.523.00) that goes in here. What additional mounting hardware (including screw that goes through the "Airbag" label) do I need?


Lastly, the socket in the door jamb which the door wiring harness plugs into is loose (where indicated by the arrow). Is this piece replacable? Do I need to replace the entire harness?


Many thanks! I need part numbers to order, with names if possible. Same post post in Polish at our club's forum. Let's see who'll be first
