I realize trigger settings are very subjective, but is there a good rule-of-thumb concerning over-travel. I seem to recall that there should be little or no rearward movement after the sear disengages. This correct? Or should there be some rearward movement?

There has to be a least a little bit of over-travel to allow the sear to reset. If things are so tight that the sear is stuck in disengaged position, the firing pin won't catch on the next round and may fire the round if you slam the bolt.
You should probably leave even more room than that because if you hit the stop, your trigger finger will have a direct mechanical link to the gun. Not good at all. There should be very little movement when the trigger breaks not because something has stopping it, but because you're squeezing it very, very slowly. During normal use, the over-travel stop should never engage.

If it's true that "During normal use, the over-travel stop should never engage", then why have it available? I do agree though with your comment about your finger having a direct mechanical link.

I have to disagree with "squeezing it very, very slowly" As long as you are not disturbing the sight alignment, you can pull the trigger as fast as you want. In particular Standard Pistol and Rapid Fire, there is just not enough time to slowly,slowly. The most important thing someone once told me was that you have to pull the trigger smoothly, not necassarily slowly.
A trigger stop can come in handy when you are not pulling the trigger straight back, it can help stop the movement of the gun as the trigger releases.

Well, that's just my rifle bias showing. My experience is that if there is any perceived movement at all, that shot is pretty much down the tube. Since I shoot rifle only, that's the first thing that comes to mind. But you're right, rapid fire does have a completely different set of concern.

I have been doing some tests on the question of using trigger-stop or not (with/without overtravel). I used to shoot a FAS-607 for standard pistol,
and the FAS does not have a trigger-stop. Now I use a Pardini SP, and I have tried to shoot it both with or without overtravel.
The result for standard-pistol seem to be that for slow-fire, it does not make any difference, but for faster shooting (10 sec.), it seems easier to recover from the recoil when there is no overtravel. I am now shooting with no overtravel, and I feel(??) that it is better.
For air-pistol, I have always been shooting without any overtravel on my Steyr LP1. Now with my new LP10, I have tried to shoot for several weeks with or without overtravel. When i change from one to the other, I need some time to adapt, but overall, the results seem to be the same with or without overtravel. But again, I have this feeling that I have better control without overtravel. My personal best in air-pistol (573 with the LP1) was set with no overtravel.

This is very much a matter if personal preference and technique. I did my best Standard Pistol shooting with a FAS 602 which, like the 607, has no trigger stop. I found that this was ideal for my technique which was based on a smooth and regular trigger cadence (with sight alignment being secondary).

I agree that it is a preference of personal preference. For me the
conclusion was to chose one of the two, and stick with it.
One of my club-mates, who is a European Champion in standard pistol,
made at trigger-stop on his FAS-602. But he removed it again. It did
not make any difference. I also tried it on the 607, but at the time
I was used to having no trigger-stop, so I also removed it from my 607.
