If you have a new Weber Smoky Mountain smoker you absolutely positively must buy Gary Wiviott's book. Although not specific to this cooker, nobody knows more about it than Wiv, and his step by step guides can be applied to a wide range of low and slow devices.
He is a purist, and Chapter 8, titled "Master the Art of Barbecue on a Gas or Electric Grill" has just one page that says "Gotcha! Shame on you for even thinking it. You cannot make low and slow barbecue on a gas or electric grill." And that's all he wrote. Well, he's right about electrics, but if you follow my tips on how to set up your gas grill, you can make darn fine low and slow barbecue on it. Wiviott, who is extremely knowledgeable about food, may seem dogmatic in his tutorial, but if you follow his procedures you will be rewarded.
