For your lighting, will there be any power source? Out in the woods consistent lighting can get tricky. Look into those high powered spotlights and get some of the window reflectors to keep the sun out of your car to bounce them off of and diffuse them. Colored plastic Report covers make an interesting filter in a pinch. We used them on
DARK ROSE: 700 YEAR ITCH and got some compliments. Be sure to hold them away from hot bulbs so they don't melt.
If you have a power source nearby, professional flood lights would be nice, but don't underestimate the usefulness of Halogen worklights (be sure to manually white balance the camera if it allows you to) or clamp lights. Again, be sure to be careful around hot bulbs.
