Luxury resources and rivers are critical for settling. Everything else is reasonably optional, as far as I'm concerned. I'll build a city to get the commerce bonus from a river or a new happiness resource every time. Other than that, it depends on my happy cap and whether I think the new city will be able to provide enough commerce and happiness to make up for everything it costs. That's a high hurdle, IMO.
Other than that, I agree with getting our section of the world up and running really well. We need more commerce, more science, more production, and more everything. We might also look at getting the new-found city-state on our side.
