Yes! The caliper pins should always be wiped off and re-greased with high-temp synthetic grease specifically labeled for caliper pins. If the protective boots that seal the pins are deteriorating or damaged, the boots should also be replaced.
In my experience (I've has 5 Hondas and I've replaced the front brakes in every one of them), if you value silence (like me), pay the money for genuine Honda OEM pads from the dealership. They include new anti-noise shims, and are always dead silent for me, even without that anti-squeal glue/lube/whatever-it-is compound. The only time they make noise is when they're supposed to--when the wear-indicator reed comes in contact with the rotor.
All the cheaper replacement pads from auto parts stores (and of course, auto repair chains) always squeek at times.
