new to smoking, need some help on the basics

I have a bbq/smoker combo and I'd really like to learn how to smoke meat. I don't really have anyone in my life to teach me. I know how to bbq, with propane, so most of my help would need to be centered around the prep, fire making, and smoker specific items I'll need. I have the smoker and a meat thermometer and that's it, so I know I'll need to get more stuff. Anyone know any good videos or articles that really go over the basics of smoking?
