Hello Aramorn, and welcome. I'm new too -- I've been reading some of these forums off & on for a while, and finally decided to register and start posting recently.
It's great to see "the younger generation" starting to discover Tolkien, and like LeeLee said, you're so excited and full of energy about it. That really is awesome. My son is about your age, and right now he's still working on the Harry Potter books. After he's done reading those, I'm going to try introducing him to some Tolkien. I hope he's even half as excited as you are. :)
Welcome aboard, and enjoy the forums.
