My personal thought is that we should go Myst -> WotE and build nothing but troops, but here is some non-biased (?) analysis:
Cahir Abbey should be growing to its new happy cap of 9, but isn't because of the overlap/health issues. Sanitation will help it grow in 18 turns if we change nothing, faster if we focus on food growth.
It takes 5 turns to build a market in the capital, 3 in Killybegs (hammers are already invested).
The next Merchant bulb is Currency, not Stirrups, and the bulb will not finish the tech.
Building a pasture for the cow will help with our unhealthiness, but watch out for lizardmen.
We don't really know what is south of us at all except for lizardmen and a few resources. At least 5 other civs are out there and could be creeping towards our rear.
Our military is 1/4 the size of Hippus, and likely 1/4 size of the Clan.
