Good information. Remind me sometime, and I'll show you The Hand Plane Book. Take a look at most of our planes; you'll see I've done most of these suggestions to ours. I haven't tuned any of the frogs, but ours seem to plane well as they are. I have cleaned our frogs and adjusted them. Given more time, I'd like to completely over-haul one plane, complete with a mirror polish on the sole. Way over the top, but it would have to look sweet!
For those who are still getting started and those who have been doing this a long time, an online subscription is pretty worth while. I would still investigate the topic further outside of FWW, but they usually are right on with their information.
