When changing a timing belt due to noises in that area, what exactly should I change?

What are the parts do people usually change along with the timing belt? I know of the tensioner, tensioner spring, idler pulley, and tensioner pulley plus water pump. What else should be changed? My car is making a a lound weird low noise when the car is driven on small roads. So does anybody know what parts I should change along with the timing belt? ALso, what else do you guys change when changing a timing belt?

Are you sure it is the timing belt.
