thamis,
I can provide you with details on Dacia, since I am Romanian...
King Decebal as the leader (you can also pick Burebista, since he was another great Dacian leader). Cities: Sarmizegetusa (capital), Apulidava, Petrodava, Sucidava, Cornyx, Piroboridava, Tariverde, Ulpia, Admaclisi.. I forget the rest, but most of them end in dava, which means city, so you can make up some if you need more. Leaders: Decebal, Burebista, Dromichetes, Scorillo
Special unit: taraboste (they were aristocratic riders). Civ traits: religious, militaristic; possibly industrious.
Hope this helps...
