Water pump, thermostat housing and radiator are do now or do when they break SOON items. Based on the experience here, you are past do on all of them.
If the shocks are original, you should replace them also. Rears are easy, especially if you do RSMs, fronts are a pain. If you don't have the right tools, find a good shop to do them.
And while you are doing the rear suspension work, check the rear trailing arm bushings (RTABS) they are normal wear items.
