V70 D5 Belts info please

[DSLiverpool]

Finally after much faffing the family car stable will be a Leaf, a Mustang and a V70, we have the first, the second is due Jan and I'm looking at V70s now after dismissing XC70s as not needed.
Being me I would change every belt and the handbrake shoes on purchase regardless (way I am)
Can anyone advise what "every belt" is (diesel motor) and rough cost / hours.
Any other preventative maintenance ? I'm looking at 2005 to 2008 cars mostly.

Cheers
