Could use some help RTW

[Steve aka Ratty / frozen rat]

I have been all across this continent several times from top to bottom and side to side,I am a just do it and learn from the mistakes kind of person but one lesson i have learned very well is, ask questions even if there was a language barrier i have seemed to get by.
Passport ,International ,DL ,CDP where aplicable ,Bike ,Vacinations plus the esentials of comfort and food are the self explanitory items that are of little worry,the information that i seek are items like what do i need to do when my DL expires where to go and does this apply to the International DL and my Passport as well ? What places or Countries do i expect to offer bribes or shall i say presents,Do i have to have a planned destination As for what my destinations or routes are going to be well does the word Gone mean much or how about that way <---> what can i get away with at border crossings.
I'm such a virgin to world travel.

I am about to embark on a Canadian style walkabout with intensions of no return,I have been reading alot about RTW travellers and thier stories but i have either missed the most important little bits of information or they were never mentioned so this is where i need some help and advice.
