not sure why you have seven water bottles, that's a whole lotta space!!!, but a camel back and the bladder will be plenty. Great thing about the bladder is that it rolls up when not needed. I only had mine filled up in Nevada.
You should be able to pack what yo need int eh wolfman saddle bags, a medium tank bag and medium duffel.
Biggest things for me were, the netbook (better options now), small stove, sleeping bag. and food/snakcs.
I really liked the Big agnes seedhouse 2 tent and the air mattress.
One handy item was the camp saw (Sven), used it twice and was glad to have it.
Plus this Trail stand
is nice to have and packs up small.
Going in Sept, yeah it might be pretty cold at those higher elevations. I only needed cold weather gear in CO and Oregon, but was glad to have it, but yeah adds a lot of weight and space.
Go through all the bearing on the bike, wheel bearings, head set and swing arm.
Here's my camp and clothing list
