I look forward to any more you might want to offer.

Any circuits or examples others have done?

For a cheap voltage reference, I would look into Analog device's AD780
series. The AD780BN has an initial error of +-1mV and is available in a
plastic 8 pin DIP for easy assembly. Download the data sheet and you'll
find sample circuit diagrams. Be sure to use a nice clean power supply and
use good decoupling practices around the device.

For resistance, see my post with a link to Digikey.
