1. The "Iron Crown" reference is to the game Battle for Middle Earth II: Rise of the Witch-King, where Angmar (the nation the Witch-King founded) is referred to as the Iron Crown.

2. I have, unfortunately read all 4 Inheritance books, I really had a hard time getting through it (it's a fairly poorly written book) but I read the First one when I was younger and I have compulsion to finish anything I start.
