Romans have Iron near Pisae, beware of them or use their Praets. Tragic map, few resources. I would ran for Alpha first, before IW. Your army seems to be not very small (F9). I would taken down barb city (north-west), but keep one or two chariots near the lake proposed by Sun. If Louis try to place new city there declare war. Put the priest back to work. You increase chances to discover Theology first and you don't have to worry about lack of money, if you have something to trade. Then adopt Theocracy and get or exchange Horseback Riding. It's the fastest way to conquer Louis. Horse archers are much more useful from their Vanilla version. You can give them Flanking2 promotion just to soften the defenders (earieler than cats). However jags with woodsman2 are also nice. The choice is yours. After IW is known I would send two chariots near Louis Iron source (if one has), just to have an advantage.
