No camp sites. There is a commercial camp ground close to entrance.
When I was there in June, you could only walk in. It was closed to cars. There is a very nice RV park within a mile of there, though.
I have been told that there is only overnight sights, for people that volunteer. This was last year, it could be different this year.
I'm not sure, I was just passing through there on a road trip.
Yes!
