the basics:

Make sure you have at least twice as much money as you think you will need
research your route, always have a fallback plan, emergency escape route
If you don't have enough money for your whole trip, plan where you are going to work first, where, for how long and who with.

Get all the usual travel books. Some may be well out dated, but they get you in to a way of thinking.

Make sure you have appropriate insurance/health cover where ever you will be

Lots more, but that will do as a start.
