I'd start by replacing all of the vac lines and thoroughly checking every component/nipple. If the canister/s were damaged, others might be, as well.
Next work through O2 sensor diagnosis and repair/replacement, as needed.
OP, what's the back story on the car? How long have you owned it? When did this problem start? You say the canister nipple was broken off by the previous owner...this should've had symptoms when you bought it.

My thoughts exactly, both the O2 issues and Boost leak issues need to be sorted.
If the whine is at idle it could be auxiliary belts/pulleys causing it.
