Chariots: go for the flank (frontal attacks often get them stuck in enemy formations), keep the enemy cavalry away from them, and whatever you do, don't give anyone on the opposing side time to throw javelins at the chariots, since they'll drop like flies. Also, find a way to get rid of other enemy missile troops before you deploy the chariots.
Heavy peltasts are among the best and most versatile troops there are.
Skirmisher Cavalry: great against Gauls and Celts, and against most low level eastern infantry. They are also great cheap cavalry that you may find yourself needing if you ever fight against steppe horsemen.
EDIT: Scythed chariots saved my butt in my Pontic Campaign. They're the only real defense I had against the huge numbers of Successor infantry.
