JellyS2, I'd also recommend that you go to the library (or, if you're flush with cash, a bookstore) and get some books on writing in general. Writing fanfic is fun, and it's great to share, but if you really want to write good stories, you need some technical skills. There are a lot of good resources out there for you. If you're really stuck on where to start, buy a writing magazine and check out the ads. I have an entire shelf with just writing references on it, and they've really helped me plan, transcribe, and edit my stories.
