If you are a stereo FM station you'll want to make the video in stereo. Easy to do. Those two RCA phono plugs need to be plugged into a pair of RED attenuated adaptors which convert the RCA phono plugs to mini-plugs. That is the end that is plugged into studio headphone jack. Also, make sure it has a headphone jack so you can monitor the audio level and make sure it's not too low or too high.
Video Make sure there is enough light.
Never shoot against windows with daylight coming through. Use a tripod if possible for a more stable picture and better video. Vary the shots, though. Don't shoot everything from the same vantage point. That gets very boring.
