As for lighting, there are several ways to go. Easiest is to get yourself a backpacker's headlamp, which ought to throw out enough light to let you see where you are going. The new-generation LED-type lights, alas, probably don't shoot out enough light, so you'll need to go with the older, more battery-intensive halogen versions. Black Diamond's Gemini ($39; www.bdel.com) is a reliable choice, with a bright halogen bulb and two LED bulbs to use when you don't need full power. You'll get two hours or more of light with three AAA batteries. Still, that will translate into quite a bit of battery consumption, so it would be prudent to get a battery charger and use rechargeables.
If not, the Gemini or the similar Petzl MYO 3 ($45; www.petzl.com) would do nicely.
And, just remember, be careful!
