First, what platform are you ripping from by chance? I want to guess it by the looks it's from a PS2 game the way it seems all flat. Anywho, to get rid of the non important parts, go into vertex mode and start deleting vertices not related to the main model you want. I'm not entirely sure how to expand or shrink models in Blender, but do know how to "scale" them in 3D Max. Hope this helps out a little bit for you.
