Ahhhh. Foam sheathing and metal let in bracing. You'll be OK. Just make sure the cellulose doesn't bulge the foam sheathing out. You also have to remember that you need at least 40% of your R value to the outside of the wall in the form of the foam or you may have condensation issues. And NO. You can not install a poly barrier under the sheetrock. Again, vapor barrier sandwich. Also you have a ton of plastic in your wall already. I personally wouldn't want to live in a plastic box if I could help it.
