For a space scene with black starry backgrounds, I'd reccommend using spotlights pointed from the directions of the light source you choose. IE: Strongest spolight coming from the sun and minor spots coming from planetary reflected light from the same source. The public library would be a good place to go for books on Photographic lighting and theatrical scene lighting.

As for light sets, I can't imagine any would really be out there unless they come in premade space scenes.
