No worries - I realize that when I posted this, I was writing as if everyone knew Unix/Linux like I do - and I should have come back and beefed these up.
For now - no easy way to edit those files on the phone - best off to 'adb pull', edit, and push back. This will change in future versions, just haven't gotten to it yet. If you have an entry in one of the files that you want to ignore, you can just delete the line, OR you can put a '#' in front of it, which tells CSM to ignore it.
So basically everything is driven by those files you just quoted - but it's easiest to edit them after a pull and then push them back ... hope this helps!
