Choosing between an image stabilized f/4 lens and a non-IS f/2.8 lens can be challenging. If you are shooting action in low light, the best choice is usually going to be the f/2.8 lens. An f/2.8 aperture lets twice as much light reach the sensor, allowing for a faster aperture and/or lower ISO setting to be used.
