I would settle my first town SW on the coast, getting two cows in the initial radius for a super-start. I would irrigate one cow as fast as possible, bringing in water through the two G tiles SE and 2 SE from the start-tile, to secure the all-important 5 food per turn. Then I'd mine and road the other cow, the BG S of the start tile, and the G W of the start. With a Granary, this will be enough for a 4-turn 3-5 Settler factory (6+8+7+9 = 30). After switching to Republic, I would build a Temple (unless we have plenty of luxuries), a Marketplace and a Harbor in this city, while letting it grow towards size 12 (those irrigated grasslands will come in handy). It will be the back-bone of my economy, giving plenty of commerce and easily 20 shields per turn after mining the hills.
The second town will be founded E, SE of the start-tile. With at least 3 BG's and 3 G's, this town will bring 10 spt at size 6 once those tiles are mined (1 + 3*2 + 3*1 = 10), which is very useful early in the game. I will probably chop the forests to the SE (using the shields to build Barracks) before mining the underlaying G or BG, rather than build an expensive Temple to increase the city-radius. This town will be the center of my military-production early in the game.
The only downside I see to this strategy is that it will take a while to get the first cow irrigated (unless there is fresh water S of them). Building a second Worker in London very early will help a great deal.
