Planning out a MMORPG

Hello all. I kinda know what I need to do. Except I was about to buy a book on planning out MMO's but the store closed. I would like to know your tips on how to do it. I need to keep organized and stuff. I don't care if it makes me go out to the store to buy some binders.. I just need to do what I need to do. There is no intentional storyboard in this game. The players "do" the game. I need help on planning this out and keeping item databases and stuff. Please help me and the most helpful tip/tips will be put in credits under 'Game Design'.
