How should I begin?  Simply delete the video sources and capture cards and *totally* start over or is there another approach that keeps the capture cards or... I don't know.

Best bet is Delete all video sources (

Also, since you're using Comcast, chances are you should look into 
scte65scan ( http://www.mythtv.org/wiki/Comcast_Users_And_scte65scan ), 
which will likely making rescanning/channel identification trivial.
