Well, being unable to tell about your army situation, I have a couple of suggestions.

Take the balearic Isles (if you haven't already), can't really see them in the picture very clearly so I don't know if you have them or not, but if you do you should definitely take them.

Then, I would say go with one of two options, if the Spanish and Julii are weak (probably not very likely) I say grab their provinces (that would be the final 10). If they look really strong then I would suggest garrisoning the towns on the frontier and then concentrating on either Egypt or Asia Minor. Just be careful, in one of my greek games the Julii got away without me noticing and came back a couple of years later with stack after stack

Egypt looks like they are having some trouble since a town right next to their capital rebelled. It might be possible for you to take Alexandria and then use it as a staging point for a large invasion of the nile delta (which you should probably start by sending in spies to cause riots ).

Also, consider picking off Pontus and the selucid province on your borders. Its very unlikely that the selucids will march through Egyptian lands (probably hostile) to counter attack so you might "auto-neutral" with them giving you some free land.
