Regarding #1: Have a tripod and use it! Set your camera to manual focus, then video your show. (blinking lights will tend to make the camera go in and out of focus) #2. Continue to use your "ride" speakers. after the taping you will replace the sound on the video with the original mp3 file in post production. #3. Check the internet for any free programs. I like Adobe Premier Elements which can be purchased $69 to $99. If I forget how to operate any program Photoshop, premier Elements, etc. I go to Lynda.com for training.
