Doujinshi are Japanese Comic Books (manga) drawn by fans rather than by professional artists. Some doujinshi follow the story line of a manga and some make up there own, but are still very good. You can buy doujinshi's from Ebay, Jpqueen.com or a vendor online. Also, if you go to anime conventions in your area, you might be able to buy doujinshi's there.

A Fanlisting is a site to bring fans of a certain subject together to create a large list of fans for each subject. The Fanlistings.org and Anime-Fanlistings.org is a large organization that holds catagories for different subjects.

I am a huge Inui x Kaidoh fan (Actually, Inui x Kaidoh is my OTP *One True Pairing*). And I started getting into Inui x Kaidoh doujinshis and before I knew it, I was pulled into Inui x Kaidoh Doujinshi world. And I couldn't be more happier ^_^.
