You want whoever does the work to use a kit like this.

It replaces all the worn out idlers and the water pump that rides on
the timing belt. Replacing the water pump is cheap insurance. If the
water pump were to fail between pumps you could easily spend $300
replacing it. It adds $60 to the job to do it when doing the timing
belt. Some bolts are one time stretch bolts. If they fail from reuse
the engine can slip and fall out of position.

The shop should have a bunch of basic timing belt tools which run
about $300 plus a Vagcom to check that the timing is correct after the
job. Paint or chalk to do a TDI timing belt is not acceptable.
