Evan,
Jordan's book is more about general techniques. Jardine's is more directed at long thru hikes and how he evolved his gear. Plus Jardine is big on making your own gear and he sells kits to do so.
Regarding packs; weights are for a medium. The Circuit weighs 36 oz (4,200 cu in). A Gossamer Gear G4 with no internal frame weighs 16 oz (4,000 cu in) and a Mariposa Plus with an internal frame weighs 22 oz (3,600 cu in). Now we are getting into different companies and BPLers can get very passionate about their favorite brands. I had a Conduit and an Ohm, but switched to a GG Mariposa Plus. The GG is just easier for me to live out of. Nothing wrong with the ULA packs at all, just a personal preference. The Mariposa Plus has a y-strap at the top that theoretically could carry a cannister on the outisde of the pack. I haven't tried it though. All these packs can carry a canister, but you cannot fit them horizotally. The canister is going to take up a lot of room. I would carry the canister only where required, and then switch to a Ursack. But keep in mind that if you camp away from the more popular sites/areas you will have less chance of a bear encounter. If you want to switch packs, it should be pretty easy to sell the Catalyst here on BPL.
Sleeping: Your most expensive purchase. I like quilts. There is no way around spending a lot of money on a quality down lightweight quilt or sleeping bag. You might want to check out the GoLite quilts. I have no personal experience with them, but prices are the best you are probably going to find. If you decide to go with a new sleep system, you might be able to sell your current bag here. One caveat, if you decide to get a quilt from a cottage manufacturer keep in mind that they are custom made and the waiting period can be weeks or even months.
Cuben strength. I am not a technical expert. Tear strenght is good, but abrasion or catching it on a sharp object is not. Plus they are expensive.
Alcohol: the most widely available fuel. You can even use HEET brand gasoline anti-freeze (yellow bottle) and it can be found in auto parts stores and other non-specialty stores. I like the Caldera Cone systems because it is almost impossible to tip it over and includes a great wind screen. If you get the beer can pot set-up, your entire cook set will cost about the same as a Ti pot alone.
