What do you change also when you change the timing belt?

My 1994 4Runner V6 engine has 140000 miles and I am about to have the timing belt changed again. Since I am going to have someone else change the timing belt, I might have them change other components as well. Usually what else do you change when you change the timing belt?

I am going to change the following components for the 1994 4Runner V6 engine:

Timing Belt Upper Timing Belt Idler Bearing Lower Timing Belt Idler Bearing Timing Belt Tensioner Water Pump AC Belt Power Steering Belt Alternator Belt Oil Pump PCV Valve

Do you think this is too much or not enough? I know the coolant will be replaced. Will the engine oil be replaced also?

Thanks,

Eddy
