I have considered also Currency and Maths two key techs. I usually do not give much importance to Calendar, neither MoM. I don't manage well specialist.
At this moment I always try to get Libraries. I think the 25% boost for research is important. Also I like Metal Casting for forges, trirremes and 1 happy face. The combination of forges and Maths yield a great hammer production.
Also with MetalCast I could try the Colossus.
Besides that, how many cities can I have without bankruptcy? With the high resources I can make settlers very fast but I will have to take care of the economy.
If the barb goes to horses that will be great, I will get XP for the chariot.
