Oops, guess I should have read this message before I clicked send.  My 
other email will answer a lot of the questions you asked below.

Mail order may be the best option for LEDs with integrated resistors ( 
http://digikey.com maybe).

Worthy goal.  The parallel port will limit you to 8 bits.  If you want 
to use the bi-color LEDs that will limit you to 3 tuners and 2 status 
LEDs (or 4 tuner and no status). 

What we did was take an Allegro Micro driver chip and send serial data 
to it to set the status of the individual LEDs.  See the mythmon README 
for more information.
