I personaly think that this is the hardest roman faction to play with. You have to go north its your only option. The only problem is money. The gauls if attacked early will be deafeted with ease make sure you kill the populance it will allowyou to train some troops and leave them there. Once you have concered most of the north and Spain you might want to move into nort east africa. these will be pivitol once the reforms come around. As soon as you get the chance move for the weak macedons the brutii rule that area and getting a good setllement will help you take them. When you take Rome the other faction capitals will b just down the road. Move another army and tak Capua. In the next few turns you should try to take salona and the move for Tarentum. BE CAREFUL!!!! The Brutii have a huge and powerful army and will be very angry that you took their town so they will attack you on every front so make sure that tou are moving troops to the towns that border with them After doing all this you have two options.
1) take your army west into the Greek area
2) continue south and meet up with your army from africa
