Sounds like I'm too late to influence this particular game, but just in general, I would give completely different advice to the rest of the thread. When I'm playing an out and out warmonger, I wouldn't even consider taking Orders. Orders is perhaps for when I want to establish an early wide empire with a Civ with few early bonuses, a Poland or a Russia. The followers beliefs to take are the ones that will turn your conquests into worthwhile possessions faster, namely Diligence, Inspiration, Scholarship, and if you have to, Thrift. Can't do anything with Thrift if you don't Annex tho.
For the founder belief, Hero Worship can work out, but you need to have a plan for the Faith. I prefer taking a founder that gives me a benefit to converted cities, and then send in the Inquisitors. Remember that the cities you conquer will both lose pop and gain it back slower than AI cities, so per city is probably better than per follower.
For the enhancer, in the Supply Cap Era, Zealotry is still a fine belief, but its no longer possible to call for a Crusade or a Jihad. I mean maybe if you build Terracotta and Brandenburg and Red Fort, etc. Does the Ikanda still have extra supply? If so, it might work well for them, but in general, if I went Authority, and am getting the per 8 units to serve as my garrisons, then I'd rather have Clericalism for the Happiness. When playing with Shaka, the limits to conquest are Happiness and maybe science, not a few units. Maybe Tithes if I enhance early, and will have people to spread it too that I'm not necessarily going to conquer. With Shaka, those people don't exist tho.
per 2 cities (and +25% yields from city states iirc).
