Shocks must have oil. That's what provides the damping. Without oil, you are riding on springs, with the result being exactly what you would expect.

Air can be optional, depending on the load being carried. The air is equivalent to spring preload.

You can change the springs without removing the forks from the bike. If you've never done a refresh on the forks, probably would be a good time to pull off the lower tube, clean out as much of the old oil and gunk as you can with brake cleaner spray, and put in new seals and bushings.

This video is pretty good:

It doesn't talk about changing the springs, but that's literally just unscrewing the top, pulling out the old ones and dropping in the new ones. The hard part is putting the cap back on. I still have the stock springs and can do it by myself without much trouble, but I've heard that it's harder to get the cap back on when you put in progressives. Might need a helper for that.

With the progressives you don't need to add air, people say. You can even find some new fork caps and not have to worry about blocking off the valve holes on the stock caps.

I've also heard that you should add less fork oil (or ATF) than Honda specifies if you install progressives. Not sure about the exact amount, but you can find that amount somewhere on the web.
