Timing Belt Tensioner on 2003 Acura TL

My car was making a squealing sound. From what I know about cars I suspected it was the air conditioning belt. My car is a 2003 Acura 3.2TL with 65,000 on it. I took it to the dealership and they said it needs all new belts to include having a timing belt-tensioner and new water pump. My question is "Does this all need to be done?" I agree with the belt, but not sure about the time-belt-tensioner and the new water pump. Would you please assist. Thank you.

When a timing belt gets beyond 6 years old, it starts to get brittle, even the ones made with kevlar, and can fail. It is like tires, after about 5-6 years, the rubber gets old and starts to crack and that is dangerous. The water pump etc are preventative measures, because, they will fail and then you have to do nearly the whole job all over. It is better to do it once and do it correctly, so it will last another 6 years.

Should I get it done at the dealership or could a certified mechanic do the job just the same? The Acura dealership wants $892.00 to replace the belts, and complete the timing belt tensioner. This does not include the water pump. Thanks in advance.
