Scenario A :

here is what I would suggest :
Destroy the Brutii with your faction leaders army, your army looks very good , and should be able to destroy the Brutii - with some command skill at least- without losing to much troops, relieving your city in the center of your empire is a must.

a hard one, mainly because their units are better class than yours, both in the field and in the city.
Eventhough ytout units are way ouclasses, you can win - with some luck involved mind you- let them take Appollonia and retreat to Thermon, when they besiege Thermon, put all your hoplites at the town square, so you won't have to deal with the routers.
Head on , you can inflict heavy losses on both Hastati and Principes, that is were your chance lies.

Trying a field battle is a dangerous thing with these low tier troops, since they are prne to rout when loosing, even if it is by the smalles margin.

Scenario B:

Wait untill the full stack located directly east of your bridge attacks.
Defeat them and take Sardis, then try and blitz Sinope and hold the mountain pass leading to Tarsus, against the advancing - neutral-Egyptians.

That;s my advice on the matter
