Hi foxracer72,
You're pretty well covered. If you'll be exclusively on trails, the zebra would probably take care of all your needs. If you are doing any cross country, take your lightest thrower and bring battery backup. In the event of an emergency retreat, try to estimate the number of hours runtime you'd need to make it back to the trailhead. Say you are three days in and need to evacuate, you would likely need about 8 to 16 hours of runtime to retreat (one or two nights and not all of that would have to be hi-beam). Chances are very remote that you would need that much light, but just in case, you're prepared.
Which part of the back country will you be exploring? BTW, in case you hadn't heard, highway 140 was closed into the park due to the fire. Check with the highway patrol if 140 is your route. Have fun and don't feed the bears.
