I prefer to take some brake fluid out of the reservoir with a turkey baster (shop used only). Brake fluid will strip paint from evbrything it contacts if you let it overflow.

You didn't mention brake flush as I guess many people don't consider it while doing a pad change. I usually combine it with a pad change and not as a seperate job. My interval is whenever it's been at least two years since the last flush. This works for me because I go through pads often enough as I only own daily drivers.

hoses and calipers should be inspected and replaced as necessary. Although I doubt most would recommend it I rebuild my own calipers.
