It sounds like I'm not up to the point where you are in terms of competence, but I know enough to say that while control of aperture and shutter speed is useful, if even on the largest aperture you still require bright direct sunlight to get a decent high-speed shot, then you have problems. F-stop on the G5 only goes to 2.4 and add that to the fact that the lens is limited in size by the fact that it's a compact (if larger than average), it means my opportunities for good photos are much more restricted. I simply don't get enough light.
That said, thanks for the tips about second hand kit. I like the sound of a 5D and lens for £750 :)
