The Lynda.com courses look promising as do Photoshop's Channel Mixer and BW adjustment layers.
Here's are book recommendations I received:
* Channel Chops written by David Bidney, Bert Monroy, and Nathan Moody. I found one on eBay.
* Oz to Kansas 2.0: The Black and White on Black and White Conversions, by Vincent Versace
I found several YouTube.com videos on this topic as well.
Thanks to all who replied.
