Insulating a prefab house

I have a Wausau prefab house in Minnesota. The walls and ceilings are panels and everything is glued together. I am thinking of using furring strips on the exterior walls and ceilings on the interior of the house and adding some 2" foam insulation, vapor barrier and then sheet rocking over this. Any thoughts or ideas on a better way of adding some insulation?

Rod,
I have no idea how a Wausau prefab house is designed or built, so I can't comment on the best way to insulate.

That said, your plan makes sense -- except that you don't need an interior vapor barrier. Rigid foam is already a vapor retarder.
