I will start by saying that everything you need to know about smoking and BBQ is on this site, and then throw in every thing you need to know about the WSM.
When "getting into" smoking, I think we all are thirsty for knowledge and looking for tips, ideas, techniques, etc. I have purchased 5 or 6 book (the recommended ones) and they are all basically the same, and not as complete as this site. I have not picked up a thing from any of the books that was not on this site.
IMHO, we are looking from something from one of the "expert" authors, for a secret or whatever. There are a lot of experts on this site, and all of the recipes and techniques are basically the same with minor variations.
Just have fun, start with a basic recipe and technique, read this site and experiment with the things that appeal to you.
