I agree with attackfinder.
You settle on the plains hill, get animal husbandry then beeline pottery for those three food squares to the north, then bronze working to chop trees.
The extra hammer will help you knock out a worker sooner, and with those cows you'll have enviable production and reasonable food very early on. Before the border pop, work that wine tile (as you're building a worker at this point, the extra hammer means production won't be too poor and the extra commerce should help establish early techs) Once the border pops work those three food plains tiles. This should help you establish a second city two north one east of the horse quickly (trees to chop to knock out totem pole to pop the borders, some grasslands for food, and of course the horses as well as the plains hills). You should end up with some very good commerce from this...
Which will help pay for the expansion acquired from the chariot rush. (If you get the timing right)
The land to the south should be secured simply by the positioning of your cities. Even if you don't quite get the rush, you'd have a very strong position.
Expanding to the sea won't help you till you get sailing. Once you have sailing, the rivers will help establish trade routes.
