The diesel water pumps are usually pretty long lasting - mine failed just shy of 300k miles, and the aftermarket replacement went after a further 60k miles.
Depending on how many miles your car has done it may be better to stick with the original pump. It is easier to replace the thermostat, housing seal and O ring than to change the pump.
If you are changing the water pump, the original gasket is a one piece for that side of the engine, and you will need to cut the little tabs that connect the water pump part to the rest before fitting the new gasket.
