Shopping list for cambelt change and air conditioning recon?

[alpenweiss2]

Hello all.our 1999 Passat wagon is long overdue a cambelt change so it's time to get the parts together for doing the work. At the same time i would like to get the Climatronic air con compressor replaced and all necessary parts for a refurb of the system, which hasn't worked for a couple of year. The old compressor was overheating so I removed the belt. Would also change the auxillary belt for the alternator etc at the same time.

I normally buy parts from Autodoc.

Can anyone advise what I need to order to have the work outlined above done. I am guessing a cambelt kit (what's the best brand of belt), auxillary belt, (second air con compressor), air con belt and any other bits?

I am guessing thw system will need to be degassed and then regassed?
Also does anyone know the part numbers for the compressor and any other bits required.

I am getting a local French mechanic to do the work, but he has asked me to order the parts.
