Ah, shielding. I honestly wouldn't bother shielding PUP cavities. It could even cause hum in some cases i.e. proximity or shorting issues. All BL PUP's are properly shielded. Just twist the PUP leads to the control cavity. Shielding the control cavity could be useful. Maybe your bridge is actually not grounded?
That's why I didn't bother shielding the cavities (the Tele already had shielding and the Strat I just did because... well, I can't quite recall where my mind was).  The control cavity might be worth it though. I had wondered about the bridge grounding, but it checked out.
