Blender And After Effects Workflow?

I want to integrate 3D animation into Adobe After Effects CS5, but I
want to know the best way to do this. I am very good with after
effects, and my friend is very good with blender. We even have a drop
box set up for this. I want to know the best way to set this up. my
idea was:

Cut raw footage in adobe premiere -> render footage segment -> import
to Boujou and track -> Give footage and camera solve to my friend ->
He Makes a model with the appropriate environment map -> He renders
JUST the model with the camera move -> I put model in After effects ->
Final color correction -> Render back to premiere

Ideas for a better workflow?
