I understand how the US Digital one's install - in fact, we installed a pair on our robot this fall for the off-season, but never figured out how to wire them up or program them.

They're installed just like potentiometers, but they have no restriction on how far they can turn. If you want, you can couple them to a gearbox shaft, or you could put a sprocket or pulley on the encoder shaft.
To couple the shaft of the encoder to the gearbox without having to buy/make a shaft coupler, you can actually use a short piece of surgical tubing, and stick the two shafts inside the hole in the middle of the tubing and put on a few zip ties to prevent it from sliding out.
