Well, for a map of Iberian tribes/peoples, Oudysseos's περίπλους της τῶν βάρβαρον Εὐρώπς: The Pillars of Hercules is a very good place to start. A lot of good information there, now if only he would do more of those for other areas! (Not a demand, just wishful thinking.) Also, for some really sweet maps from all over the place, here's the link to his parent thread: περίπλους της τῶν βάρβαρών Εὐρώπς
I remember also seeing a link to a website which provides fairly accurate political world maps from various periods in History.
Hope I could be of help!
