So as far as Thancred and Reno are concerned, they'll choose to go to the coordinates that match up with Mat's last known whereabouts to see if they can find anything there.
I have another idea of Thancred and Stephen (which I'll cover in a different comment), but beyond that, he'll be taking the map/ledger back to the castle to distribute the information to other Summoned who are investigating so they can potentially follow some of these leads as well.
As a note, if possible Thancred would make copies of all of these items rather than taking the originals. I don't know if he'd actually have the time for that, though, so if he had to just take them, he would.
