At this mileage, it is a good idea to perform these services, it will help to limit any issues later with these items. Just as the oil in the engine needs to be changed, so does the oil in these components, and 60k is about the right time to do it. I would see if they are willing to cut you a deal if you do all 3, or call around, this is a very easy job and can be performed by just about any shop, even a quick lube shop. Just make sure they use the correct fluid.
