I would definitely have at least a front brake and free wheel for coasting. I like the idea of a flip - flop rear wheel so you can have 2 gears to choose from. If I remember right there is even a 3 speed rear hub with some sort of control mechanism attached to the handlebars. Three gears would really help when carrying all the things you need for touring. In fact, if memory serves, think I've seen some bikes with even more gear choices, which would really make sense for touring, but those bikes are rare and really hard to find. (control / Alt / Sarcasm / Off) Have fun, whatever makes you happy is the right bike for you.
