FBX Export Help (Deadline Looming!)

Short version: I'm working with a group, we got rigging and animation files from someone we can't reach, there are issues, I'm an environment modeler with one animation class of experience trying to fix their stuff, we have a hard deadline this week.

1: I've got the source files in Maya (my experience is in Blender and 3ds Max). The rigged models are too small - they're 1 unit = 1 cm when they were supposed to be 1m. They need to be exported to FBX for use in Unity3d. I see that the fbx exporter has settings for scale factor that sounds like it could convert it to the right scale and the alternative sounds like setting up a controller, linking the rig and model to it and using that to scale; I barely remember how to do that in Max much less Maya.

2: WTF are BlendShapes? In my tests, it's appearing in Unity as a separate copy of the model offset from the main; it's not visible in Maya though there is a group in the object hierarchy for them. In the context of the model, I think they're linked to facial animation.

3: Are the bone controller handles and such supposed to be included with the FBX export?

Least anyone asks, no I can't share the files for contractual reasons, sorry.
