Have to agree with most of the above really.
Iron is essential, as you come up to finish IW in the tech tree, be ready to send out a settler to sit on a decent chunk of iron if you have none in the capital, or ally a CS and pay to upgrade the resource.
Build up a decent fleet of SotL's. I like to have 2 "navies" of 4, each with their own Privateer. If I'm going across continents I'll often either take a coastal town, or found one as my "beach head" to land my longbows and melee units to take internal cities. Longbows are excellent, and they upgrade into gatlin/machine guns that have a proper range.
When played properly, England is a very strong domination civ.
