RE: Headlamp help
Check out the Petzl E48P Zipka Plus Headlamp. It has no weight and has multiple light settings as well. Burns from 80-400 hours on a set of batteries. What I like most is the lack of a headstrap. Instead, it uses a heavy retractable thread. It can be worn on your head (of course), your wrist if you're skinning after dark, or wrapped around anything. VERY useful.
