Hey Whuppinstick,
I've been following your trip too. I've adjusted my idea's of what's possible and what's needed.
I'd love to hear your approach to hunting Westside Elk. You Da Man. 
Good! It helps a lot to do a couple practice backpacking trips, both to understand what 30, 40, or 50 pounds on your back means 10+ miles into a trip over rough terrain and to learn what you can get by without. For instance I would never carry a medical kit beyond some athletic tape and a needle, but I also never get hurt or take pills. For me that works, for others maybe the peace of mind is worth the weight?
For westside elk, all I can suggest is darn good rain gear.

Also probably a heavier duty tent. But with the availability of water on the west side I definitely would not be carrying a water filter; I'd be drinking straight or using Aqua Mira (If you live close to Canada go to MEC in Vancouver and get Canada's version: Pristine).
