Welcome James, and good choice on the chicken to start with. Make sure your wood is seasoned, green wood will leave a bitter taste. I usually do leg quarters at around 225 to 250, mainly because I got other stuff on and that's where I like to smoke, when I grill I always do them at 300
So you got a lot of room as far as temp goes, just keep an eye on them if they start looking to dry you can spritz them (I use apple juice) spray bottle and juice. I brine mine about 6 hours before I get ready to cook, salt, sugar, Tony's (or what ever seasoning you like) and water then I pat dry, rub them down with olive oil (any good oil) sprinkle whatever seasoning or rub you like and on the smoker. Sometimes just before they are ready to come off I'll baste them with BBQ sauce, kinda depends on what I am in the mood for.
Be sure and let up know how they turn out and Pictures !!!!
