GAS GRILL DIRECTIONS: In small bowl, combine all rub ingredients; mix well. Cut ribs into serving-sized sections. Rub mixture over surface of ribs and chicken. Place in shallow dish. Cover; refrigerate about 1 hour.
When ready to grill, prepare grill for cooking with indirect heat. For dual burner gas grill, heat only one side; heat grill on high for 5 minutes.
Reduce heated side of grill to low. Place ribs on unheated side of grill; cover grill. Cook 2 3/4 hours, turning occasionally.
Add chicken to heated side of grill; cook 45 to 50 minutes or until chicken is fork-tender and juices run clear, and ribs are tender, turning occasionally. (Ribs and chicken cook at the same time.)
