Hi Ike, you won't need bug spray, but you definitely need bear-bagging gear. I would carry a little sunscreen just in case.
On the shuttle front, I don't know of any commercial shuttle services, but I would be happy to help you out. I live really close to the areas you'll be hiking through; I could certainly shuttle you. Haven't checked if you are set up for PMs, but if so, I'll shoot you one in a few...
