In the end I didn't settle in place, I moved SE. Set about producing a few warriors to scout out the land and pop goodie huts (3x gold, 1x scout). Animals killed all of my units before long which was annoying, but not before I'd met Perciles and scouted his city for rush potential.
Met the AI in... Perciles 3440 BC, Hatty 3280 BC and Caesar 2760 BC. I can't think of three more... harmonous... neighbours to share this Island with
I settled the second city near the horses to the north (have been favoring chariot rushes of late), getting both horses and putting my staging city closer to the victim, Perciles. A third city was founded but the goal of this was to continue producing workers and settlers while the other two helped in the war effort through whipping and chopping. It didn't really, no hammers, but it'll produce some commerce so

During the war on Perciles I destroyed his copper mine, but that didn't seem to stop him producing more Phalanx which was very annoying

But I did get his capital and three workers so not a bad day out.
My standing army is getting a good workout, there is a continual stream of barbarians coming from all directions.
Going Forward:
Intention is to settle a nice little commerce city SE of the capital, on those dyes and rice. Then get at least two of the 'production' cities I've labelled to the NE. Reducing the amount of land Hatty and Caesar have to play in is second on my list to becoming financially better off (cottages).
Still need to explore to the west. I don't know who is there or how big the land mass is. One early objective is to produce a couple of work boats and scout the coast line.
In the future Hatty and Caesar will fall to my Camel Archers, because I just don't like them and if I have to live next door for another 2000 years I'll go nuts
Objective: Domination victory.
What I learned so far:
1. Take more horses if you're rushing Perciles, his Phalanx hurts.
2. Think a bit more before rushing to settle early cities. A lame duck (few hammers) can hurt early productivity.
My empire to date, with optimistic dot mapping in place...
