My advice is to stop and say hello even as a nonrevving pilot.

Whenever I nonrev on AA or Eagle, I **ALWAYS** stop by the cockpit - whether in uniform or not - and introduce myself as a nonrevving pilot and thanking them for the ride.

I do this because I greatly appreciate it when I am the one working the trip and someone does it for me. It is very reassuring to know that we have pilots (or FAs, too) on board that can assist if needed. It's also a professional courtesy.

Jumpseating on USAir is a wonderful experience. They have been nothing but great to us. Yes, occasionally the F/A will tell me there is no need to say hello up front, but I always plan on doing so anyway.
