Starting Techs (Agriculture + Wheel) means you can easily start with Animal Husbandry and get Chariots running super-fast.
The +2

you get from the Hammam will balance the +2

you get from Expansive. That plus the Organized trait really encourages REX at/before Code of Laws (b/c of cheap courthouses), then growing the cities to super size. This means building a fair number of farms, to get your population up quickly. The 50% civic cost from Organized is best exploited when running high population and expensive civics (Caste System, Organized Religion, and Bureaucracy)
Hereditary Rule will be key to getting super-sized cities up and running, though Representation + Caste System might be the best way to exploit your huge population. In any case, you'll want to exercise some restraint with the

in mid-game, so you can get big population numbers.
Tech-wise, you have a tough choice at Liberalism. You can grab Nationalism for drafting, then research Gunpowder manually. That will allow you to get massive #'s of Janissaries (and your Globe Theater city can draft them w/o unhappiness).
However, you may consider grabbing Gunpowder instead, and just building your Janissaries the old-fashioned way. That would allow you to keep running the reduced-priced Bureaucracy civic, or (even more interesting) Vassalage.
Can you win a conquest victory with Janissaries? That would be interesting: beeline to Gunpowder, build Janissaries, conquer the world! In this case, you wouldn't need Liberalism at all, and Vassalage would probably prove more valuable than Bureaucracy for that final push.
