Nothing unique about this area in these terms. Do what works for you. Currently, I'm liking my Steripen.
I just hang my food in a nearby branch. Get it off the ground, that's all.
I'm unaware of a company that runs shuttles for grand gulch. I'm sure it exists for a price. I just walked from the trailhead to pavement (barefoot, on the sand, one mile) then hitched. VERY light traffic, but the second car picked me up. It looked like most other people were using bikes for the shuttle.... That'd be a good plan.
