Do ground screws used to to ground metal boxes have to be listed & do they have to be green?

No. I think they are very handy to use and I installed my share of them, but they are not a requirement. you do have to bond the boxes (250.148), but in my opinion as long as you do not use a sheet-metal screw, you are fine.

Just to add to Ryans answer, for the people that might not of crossed this before.
250.8 prohibits the use of sheetmetal screws for grounding.

I will add that many times people get hung up on 250.126 Identification of Wiring Device Terminals.

This article says the ground screws on devices must be green.

Article 100
 Quote:
Device. A unit of an electrical system that is intended to carry but not utilize electric energy.


250.126 has nothing to do with the screws used for grounding anything else.
