It isn't necessary, however advised. Generally if the water pump goes this can cause the cambelt to wear faster than normal, plus considering the life of a cambelt, wouldn't you rather make sure that your motor DIDN'T break a piston and valve?
In saying that, if you have just done the cam belt, don't bother.

It is not necessary to change timing gears when changing a timing chain unless they have become worn. You won't know if this is the case until you get the cover off and inspect them. It is necessary to change any chain tensioners when you change your timing chain.

It is not recommended that an amateur replace a timing belt in a Holden Barina. One would have to take everything off from the front engine cover to just remove the cover. Then, there are marks on the crank pulley that needs to be lined up to replace the timing chain. A licensed mechanic can help you with any questions.
Necessary, no. Recommended, yes.
