I think marco's advice sounds really quite helpful, whatever your opinions on details like shoe/pedal choices. Don't take loads of guff. Don't take a spare chain: just fit a new one before you go. Don't take spare tyres: fit new ones before you go (might be good idea **not **to use a bike with 27" wheels, btw, in case you do need to buy a new tyre out there... stick to 700 or 26").
Have a think about loading more of the weight up front (lowriders, bar bag) than behind you on your bike, this will help in ascents, apparently. I think you can get a lowrider rack that can clamp onto any fork, or find a fork with the relevant bosses/eyes.
