Mazda 6 Diesel - Servicing - Can belt change - Gee-en

Hi. My Mazda needs a major service (75000 miles) and the cam belt is due for a change.

It is not the latest model but the one before registerd in '07

You always recommend changing other bits and bobs at the same time (tensioners and plastic pulley wheels etc) What specifically should I ask the garage to change when renewing the cam belt on this make and model?
