If you are using flash the shutter speed will have virutally no affect on action or exposure as that will be taken care of by the flash -- just set the shutter speed/aperture so that you can see enough to frame the shot.
If you are using the internal flash you can adjust the aperture or both {shutter speed and aperture}.
With external flash you will need to have a fixed aperture to match the flash setting. With this method you can control the degree to which the ambient light will affect the exposure, so you can lighten up the background by decreasing the shutter speed/opening the aperture and brightening the EVF or LCD.
Of course, if the shutter speed goes too low and there is subject or camera movement you may get some blur.
