There's usually only ONE vacuum hose that's problematic on turbo cars with your mileage and the rubber elbows disolve at each end from oil in time. Both elbows can be replaced without removing the intake manifold OR you can bypass the original hose with another and run it on the outside of the intake manifold (not under it). One end starts at a nipple behind the PS pump, the other end (where it comes out) is near a sensor, near the air intake tube that goes into your turbo (close to firewall, low).

A vacuum leak in itself will trigger O2 sensor codes so fix the vacuum leak(s) first and have the O2 sensor codes erased BEFORE replacing more parts as it's probably not needed.

As for the brakes, if they're not problematic to you and the pad thickness is still good, do nothing as it's also not needed.

I've never seen both Evap and compressor leaking at the same time so get another opinion on that one too. Did the car already have dye in it and did they then dye check the car or are they guessing?

At 70K miles, do have the timing belt replaced if not already done.
