What I did was put teflon powder on the felt bushings (3 of them), and on the key pedestal felt (the felt on the end of the key that pushes the hammer up.
This is where I got my teflon powder:

The dudes there were very nice, and shipped it that day.
I purchased my brushes at the local art supply store.
I got one broad brush, and one finer brush, but I really only used the fine brush. Make sure to get natural hair brushes instead of a brush made out of synthetic polymers.
Also, a SAFETY PRECAUTION: I wore gloves and a face mask AND had an air purifier running right next to me. Inhaling particulate matter is always nasty, and the fact that it's teflon is no better.
Once you take off the name rail, the keys just lift right out.
Just lift the key at the front, and pull it out being careful not to hurt the hammer/damper assembly.
This is what it should look like.
I took off the harp, but you don't really need to.
This is the bushing under the key:
You don't need to put as much teflon in these bushings as you do the key pedestal.
This is the key pedestal:
I coated it liberally with the teflon powder.
I probably should have replaced the felt on these, but the teflon improved the action significantly.
All in all, this probably took me 2 hours.
It greatly improved the action of the piano.
Next, I'm going to adjust the timbre of the piano.
I hope someone finds this shit useful.
