Seems reasonable. I assume one of your lights is on the left and another on the right, not two on the left.

Better sound recording would definitely be your best upgrade; you may be able to pipe your phone camera in to your PC as a video source (search DroidCam), in which case you can set up for simultaneously recording audio through some better channel – your initial capture determines the extent of what you can do with it, so a good mic -> USB is probably what you want.
