Cambelt parts

Hi,

I'm looking at getting the cambelt and water pump changed and just need to make sure I am ordering the correct bits, my car is an AUM and i'm getting the bits from GSF

I take it a need: -

12986 Cambelt kit

13404 tens set

17062 Water pump.

is there anything else I will need before my mechanic laughs at me for only getting half the stuff?

many thanks
