Please take photos if possible so maybe we can make a photo guide of it,
btw most of the photos for a photo guide are best taken when you are putting evervthing back together, so as you are a bit more familiar with the parts and they are usually cleaner as well so people can see better,
Your own photos taken as parts are removed are also a help for you when you try & put everything back together.
Assuming you have full acess to the underside of the car, I.E. hopefully its on a lift bridge?
1) Remove exhaust clamps & rubbers holding the centre silencer box, remove box,
2A) Carburettor engined (motorcode GU) car, remove the 6 bolts holding the twin front silencer box to the exhaust downpipe, remove box, carefully move downpipe out of your way.
2B) Injection Engine (motorcode GX) car, trace the electrical cable from the lambda sonde mounted on the catalyst (front silencer box)to its plug under the bonnet, remove from plug then remove any cable locating clips, remove the 6 mounting bolts as in 2A & remove catalyst c/w lambda sonde.
3) Remove the sheet ally tunnel heatshield(s) these are held in with round spring clips that will break when you remove them (VW p/n N 907 965 02 & they cost next to nothing each so get some new ones!
You now have full access to the propshaft.
4) Using the correct tool loosen the 6 bolts holding the cv joints to the propshaft centre section,
then loosen the 3 bolts holding the propshaft front section donut to the transfer box, do the same with the three bolts holding the rear section donut to the VC unit,
btw leave one bolt on each end finger tight to support the shafts or you can damage the rubber boots on the shaft CV joints, and you really dont want to do that as they are only available from VW and cost about 50 pounds each, (yes thats right 50 pounds just for the boot)
You now need 2 people here, 1 can hold the shaft outer in place while the other removes the remaining bolts, now remove the outer shaft & repeat at the other end.
5) With someone holding the propshaft centre section in place remove the 2 bolts holding each of the bearings in place, remove centre section
6) You can now remove the bolt in the centre of the drive flange remove the flange and then remove the bearing and replace with the new one and refit everything [

If everything goes smoothly it should not take more than a couple of hours at the most, I would suggest spraying all the bolts with a loosening spray before you try & remove them.
