Internal Trade only should be rather clear, only send goods from our cities to other cities of ours.
"very carefull" external trade means, we will sent goods to nations who like us as well, if the trade route will assumingly pass no other or as well friendly territory to prevent any pirating as much as possible.
"carefull" external trade means we will send goods to nations who like us, regardless of what lies in between the sending and the receiving town.
"full" external trade means, who will pay the most, will get it, regardless of their attitude.
NOTE: as i'm often quite surprised by the way some trade routes use in my own games, i'm not very competent on the "aspected route" question, but i'm rather sure some people around here will know more about that.
