So starting with the stuff numbered:
1-4 Just correspond with what they type of object is I think. So 1-2 are the mesh, 3 is it's modifier's (which you can view in the button just under #6)

5. Is World
6. Is Object
7. Is Vertex groups
8. Is Material

You should be able to move the Bag into place using Object mode or In the Object settings in #6.

Vertex groups are used for bone weights (which ties the parts of the mesh to a bone) and shape keys (which is for things like facial expressions and lipsync)

I'm not familiar with the importer plugin in blender, and I've only used CATS once before when fucking around so I don't know if that could be messing something up.
