What paperwork, if any, is required when traveling legally in NJ. Say going from home to range. FID card, copy of permit to purchase, certificate of eligibility?

None required.

It's nice to have your FID with you. It might save you a trip to the station. But not legally required to be carried on your person.

COE and PPP copies are useless on the side of the road.

Nothing needed.

I have a picture of FID on my phone just as a incase, came in handy once, was in a store that rule was I cannot handle without my card, didn't have card with me,  but accepted the photo. 

Great, thanks for the replies. Photo is a good idea.

Well that depends. If you are driving, you need a drivers license. If you are walking, you don't need anything. You don't need to carry any paper work related to your firearms.
