What components should be changed at the same time as my 2005 Skoda Octavia's timing belt?

I own a 2005 Skoda Octavia with a 2.0-litre 140bhp Volkswagen PD diesel engine in it. It has done 70,000 miles and I want the timing belt changing at the next service. As well as the belt, what else needs to be changed?
Best to change the tensioner, all small plastic/nylon pulleys and the water pump.
