There were a couple of backpacking threads recently that have good info.
A tent big enough to stand up in is going to be f-in heavy. I second the tarp idea, especially if you need to pack up quick and carry it. It really depends on how often you'll be expected to carry it and also how often you'll be in a larger, well stocked fire camp. As far as fast and light gear goes, REI is better than Cabelas. IME, stuff designed for hunters tends to be heavy and bulky because they assume that ATV or vehicles will be fairly accessible. Backpackers are all about the distance hiking, so the stuff is designed specifically to be light weight, compressible, and fairly rugged.
I worked out of Susanville a couple of summers ago. I love that part of the world. Absolutely beautiful, the Great Basin, up the eastern Sierras, and over to the coast. Congrats.
