Based on how I read the website, camp fires seem to be okay, although you may not be able to during different parts of the year. Also although it doesn't explicitly say so, you may have to use a fire ring. You do in many other places.

I doubt the authorities will bother you much for flint style lighters, especially since matches are far more similar to fireworks and if fires are allowed thats what most people will be using to start one.

As far as your other questions, they'd probably most easily answered by calling the ranger station and talking to them. I went to college with a fellow who never used informational websites and simply picked up the phone and talked to a real person. I like websites myself, but some questions just aren't going to be answered there.
