The "Weber Smoke" book is a good place to start with some easy recipes. Some grilling gloves and some kind of temperature measuring device are essential. I use a HeaterMeter to monitor/control the temperature of the pit as well as monitor the internal meat temperature. As a beginner, you could use any Maverick/Ivation type thermometer. To simplify igniting your charcoal, you might want to take a look at the Weber Chimney starter.
Hope this helps! Welcome to the forum!
