Hi Chuckk,
See the thread from Friday called "Naming multiple alsa sound cards (was Re:
synthetic sound generator with api)" which has some clues on that.

As for Audacity, AFAIK the Debian version doesn't play with jack yet, only
plain ALSA. This link has instructions for building it specially to do so:
http://www.nabble.com/Re:-Audacity-will-not-work-if-JACK-is-running.-p3229677.html
but it's not the "Debian way".
In the meantime, Rezound (similar style to Audacity) or Ardour-gtk (fancy
multi-tracker) are both jack-aware audio editors, as is the deceptively
simple-looking Snd-gtk package.
Good luck,
John
