Thanks for the quick responses!
I know when I started out I was rather uncomfortable wearing Lycra. Its been 9 years now and I wouldn't think about riding with out wearing it. I'll carry a pair of soccer shorts that role up into nothing that I can slip on when not on the bike for wearing around cafes etc. I think I'll stick with the Bibs then since they are comfortable and what I am used to now. I have some full zip jerseys too and usually use my jersey pockets to carry a small multitool, a snack or two, and cellphone. That will change when I go touring.
I think Ortlieb Panniers are what I'll settle with. Since I am essentially soloing this tour, I will need to be able to carry everything with me. A handlebar bag would be useful if its one of those that has a map leaflet in it. No GPS, so printed directions for the trip (and some land-nav most likely). Its been a while since I've used a handlebar bag (i dont think my last tour used one).
