Hi,
Those tabs you speak of hold the body to the floor, they will move inwards towards the center to free off the body. No screws hold the body to the (coach/combine) floor Those screws hold the black floor (that has the trucks etc on it) to the internal (with the seats) floor.
The partition fits into a couple of fixings on the floor, and should be able to be left in position; the freight doors should clipback in position, but to help them temporarily fix them in position with some masking tape cos you won't have enough hands!
They fit into a space left on the coach floor - the part with the seats - there is then a seaprate floor that the bogie trucks etc fit onto.
