With a 5.6 aperture the lens will not be good enough for nighttime action shots - which is why you will need a flash for the cheerleading. Even an f2.8 lens would likely be insufficient since the lighting will not fall on the cheerleaders but the field of play. F2.8 and ISO 3200-6400 would allow you to shoot action on the field but if you want to shoot the cheerleaders off the field then flash is the only way you're going to do it well.
