Tripods are best used for long exposures, awkward camera placement, when you want to very precisely align your camera, or when you want to keep movement to a minimum (Macro comes to mind). Your lens will probably be a Canon 18-55mm IS, and the Image Stabilization in it will fairly well negate the need for a tripod in some cases.
First thing you should do with your camera is not use it in Auto mode. (The green box)
