I have changed the tensioner and idler pulley also. They cost me $80 extra, BUT
when I've looked at the tensioner closer I've found its bearings are getting loose already, so it was I'd say right time to change it.
I installed Dayco belt/pulleys, so far so good... for 1 day.

BTW, the broken water pump and tensioner were original Toyota parts, nothing lasts forever.
NGK may produce good belts/pulley also.
Also, you may consider changing PS belt and Alt/AC belt, but you can do them anytime later, I think it takes 5 min or so to change them.
Or, almost forgot, you may need a timing belt cover gasket!!!! I've found I need it in the middle of my timing belt work and it was not available in stores at the time, so I have used some black high temperature "liquid polymer" (??) gasket from Autozone instead.
And make sure you rent right puller for your pulley (the pulleys can be different, so look at the pulley first before going to the store).
