Side luggage compartment trim panel (Oct III Combi)

I have managed to remove the tailgate/luggage compartment cover trim as well as all the visible screws and hooks on the side walls. I can't seem to figure out how to:

a) take off the side luggage compartment trim panel (perhaps because there are screws which cannot be accessed until you take the rear seat off (or at least the bench)
b) take off the roller cover assembly as well as the variable boot floor.

Anyone have any ideas how to do this?
