well first off rands first power acquisition fever occured in baerlon in his ecounter with the children of light.

warder bonds do indeed tell in which direction the bonded is,we see this through out the books.the further away the person is the vaguer the direction gets,we see this when elayne comments on how rand is jumping bout all day (not sure wich book),how he is in the east then the west etc.

as to the thom/domon case you don't rememver everyone you see,and domon did give a look which hinted he might have recalled the gleeman,there is debate about it.

and weren't the trollocs asleep when perrin and the others killed them?when they all got killed slayer had directed the trollocs to an ambush.

yes...i think ltt was definately aware of moridin before rand himself was,i think this is due to rands "hardening" of himself
