Yeah, I'm quite a noob when it comes to trace scenario lineage, Phoenix.
In most COTA maps you'll see that contour lines intervals are considerably higher than what you find on the Netherlands or Belgium maps. So a map that looks "similar" to a Dutch or Belgian map, will actually be portraying much steeper slopes. Generally speaking, is very bad country for heavily motorized units - they'll be confined to roads at the bottom of valleys. As far as I know, that's quite a theme in the Spring 1941 campaign for Greece.
Dismounting capabilities is something in the TODO list - it's going to happen, sometime. In the meantime, one thing that would work nicely is to modify the estab introducing "dismounted" versions of the forces involved (I think you're already doing something similar). That would indeed account well for motorized infantry leaving behind their trucks, etc. provided the scenario is short enough (1 or 2 days).
Regarding VP locations: if you want the scenario to present more varied results, break down objective areas into smaller ones. That should broaden and diversify considerably the possible resulting outcomes.
