Go get a Sony DCR-VX2100. You can shoot your entire project with with one of those key chain lights as the prime light source. Just bounce it off the cieling if you need it to be diffused, or shine it through a toilet paper tube for a follow-spot effect. Outdoors at night you can just use available star-light. You just have to watch your angles because the stars make multiple shadows, (like on a stage with lots of pin-spot light sources.) And if the moon comes out you 'll have to use a neutral density filter to keep from over saturating. For a warm/fuzzy glow look you could use a candle... with a filter in front of it.
