Preferably need a special offer!!

My cambelt is due next month at 4 years old and 50k miles done.

Does anyone know any garage doing offers or good prices in the area around the north east?

Am i right in asking for the following ( ihave done a search but i'm getting confused now)

1. the belt naturally
2. tty bolts (read this on another thread)
3. tensioner
4. water pump
5. do i need any other belts doing while they are in there

Also i need to change the gear box oil soon is there anything special i need to know about this or is it as simple as oil out and replaced?

How often should the desiel filter be replaced?
