oh man, that sounds awesome, inspirational, and I'm officially jealous!
Specific gear depends a bit on what kind of photography you're planning on focusing on and how your getting to where you go. Driving all the time? Will you always have your car as a "home base" to store extra stuff you don't have with you?
Something to hold it all, make it a nice modular system. Maybe a way to take a subset of that with you if its raining.
www.thinktankphoto.com makes terrific gear belts n pouches. I highly recommend their stuff. I also have a number of them, so if you have "what do you think of X" questions, shoot me a message.
I took a lowepro slingshot 200AW with me to London years ago. PRO was that I had all my gear QUICKLY accessible in a unobtrusive looking sling bag (1Dmk2, 17-40,70-200,85,flash). CON that I discovered the hard way is that after many weeks of all that weight bearing down on one shoulder is NOT a good thing. Recommend the bag for short trips / days... but not for long days / many days.
Take a look at
www.lensbaby.com , it might fit some of what you're doing on the inspirational side of life. I've had a Muse and a Control Freak for many years. I rarely use them, but they're loads of fun when I do!!
