I think the HO wheels are all the same, but I'd have to look more specifically through Gary's guide and other sources. Incidentally, my plan for the HO vehicles was to maybe buy a few in the worst possible condition, so as to a) save money, and b) not feel bad about disassembling them somewhat! I do think they often share a common chassis as well, but I'm pretty sure there's more than one version of that.
the other plate is atleast a new variant (maybe even an own part).
it connects to a different type of door (tilt door/double doors).
it also has a different amount of studs and is for different cars.
the old one is narrow, it only fits the H0 cars. (13 side studs)
the new one has a 4stud wide ramp. (14 side studs)
Peeron has two entries (820b and c) which seem to be the same part. (still only one set: 348)
the doors are missing in Ldraw too, they are the same for right/left and are an assembly with a torsion spring.
the eight-sided stud can be rotated and locks in the base / the roof.
