Just general comments:
Which Canon 70-200 L ? The f2.8 or the f4.0. Since you mentioned action shooting, I was thinking perhaps you meant the f2.8, but then this is quite expensive too, so probably you mean the f4.0? For action shooting with random movement (rather than panning), you need fast shutter speeds, so IS might not help that much, while for portraits, candids, or even wild-life (for some wild life, 200mm may not be nearly enough reach ) it can be very helpful (sort of instead of a tripod). IS in the lens is nice because it also stabilizes the image in the viewfinder.
If you shoot with a speedlight in conditions where ambient light is much darker than the flash, you don't need to worry much, the flash will freeze all motion, since it's so short.
