I've just done the belts on a VW camper with the same engine and marked the pullleys and the belts then marked the new belts then refit to the marks ,,, remember two paint marks for the camwheel ,
Waterpump was ok , this is the cause of many snapped belts on this type of VW engine ,,,
I've just bought a later one 2001 with the 2.5tdi with both belts snapped ( which I thought very strange ) with only one bent valve ,,, and camshaft in three bits ,,, I think the fuel pump end of the cam has a slot in that a 4mm? piece of steel will fit this lines up with the top of the head ( needs to be evenly packed ) , then there's some dowls that fit some of the pulleys ,, Will try and dig out engine manual should have part numbers for the timming belt setup tools ,,
crank bolt has a high torque setting that is a stretch bolt ( I've re-used them no bother ) does yours have the V or the flat belt driven alternater
