Well that round certainly went as well as you could have hoped. The decision to go after Mehmed certainly seems to have paid off. You're in such a dominant position that it appears that the result of this game is no longer in doubt. Certainly a big difference from the last ALC game where you went into the last round not knowing if you win or lose. 
Even economically I think you're in a much stronger position than the current GNP standing indicates. Things will improve dramatically once Bursa comes out of revolt and Edirne grows some population and gets a border expansion (BTW Edirne and Bursa should be building culture until they get a border expansion). Add in some multiplier buildings and I would expect you to move quickly toward the top of the GNP standings.
As to who to attack next, I think arguments can be made for either JC or Freddy.
As many have pointed out, JC is your main rival and taking him out now will prevent him from getting stronger. To be honest I don't see this as a major issue as JC's UU has already seen its best years, and you have a substantial production advantage on him. Still, attacking the strongest AI and leaving the weakest for later is usually a good play.
OTOH Freddy is so weak that you can begin an attack on Germany almost immediately where you'd want to do some build up before attacking Rome. Attacking Freddy also doesn't leave your core cities exposed, and in fact since JC is pleased with you I don't think he would join in on Freddy's side. You would rather quickly acquire some good cities including Cologne which would make a good HE city and Berlin which would make a good NE city (if you're willing to wait a bit to build those National Wonders). And you've already pointed out that a quickly launched attack on Freddy also might help you get Liberalism.
If you want to build HE in one of your current cities I would recommend Tokyo. Remember that the only reason Kyoto has the most hammers is that you are running Bureaucracy. Given the number of towns and soon-to-be towns you captured from Mehmed you'll probably want to switch to Free Speech relatively soon. Also putting HE in Tokyo means it can speed up the building of ships, and you're going to need a sizable navy to invade the other continent.

). Still there are enough matured cottage tiles available that those cities should pay their upkeep at least.
