Rich Hunt as Richie 3-Jack did made a good effort at clarifying the book a bit. You might try there on his blog.
Personally, while I also find the Yellow Book complicated, I wouldn't live without it and use it often for clarification and edification. I suggest you take it in snippets.
As with me, keep it close at all times and just look. I think the more you use it, the more acquainted you will become and the more useful it will be. Granted, it is very easy to get frustrated.
