1994 V6 timing belt parts question

I have a 1994 Toyota V6 3.0L 3VZE engine with 140,000 miles.

The timing belt was replaced back in 1999 when it was in for a head gasket recall.

The idlers, water pump, and tensioner are 18 years old with 140,000, the belt has 100,000 miles and is 13 years old.

My Toyota dealer where I got the truck quoted me 1200 to replace the belt and water pump. I think not.

Today I took the front of the engine apart and all I have left to do is pull the balancer from the crank shaft.

I plan to replace the water pump and belt

So here are a few questions for those who are in the know.

Should I also replace the idler at the tensioner on the right side? Should I replace the larger idler on top located between the 2 cam wheels? They both spin freely.

This is a lot of work. Such a deal 1200 to replace a belt and water pump. Some times I think we should have stayed with push rod motors. I can't imagine how much work it will be to do this type of job on a new Toyota let alone something like the new Ford Ecoboost.
