Various points re: England's econ strategy.
Oh, I don't disagree that the strategies you've outlined can be good. In fact, the Big Ben + Commerce mix is something mentioned in the England strategy guide in the War Academy. Great Merchants + Pentagon are grand, although the GM can often pale in comparison to a properly used GS or GE, and the Pentagon comes rather late. That said, you're bang on the money nonetheless. Not too sure I'd recommend Honour, but I can see the thinking behind it.

How to play England on Huge/Immortal/Small Continents - problems listed.
I play Immortal/Small Continents myself but usually on a Standard or Large sized map, so take my advice with that in mind.
In terms of wonders the priority with England is Great Lighthouse/Great Library and then HS/PT. After that it depends on playstyle. Whether you go for the Lighthouse or the Library is based on difficulty. On Immortal the Library is better, the extra speed and sight might matter more if the AI was more competent at warfare but as it is the real fight against the AI is in the economy and for that the Library wins out.
The Astronomy beeline can leave you weak in military techs. Geography, especially in small continents, is your friend here: ideally you'll have your own island so secure entry routes to your island early on and don't allow open borders with your neighbours to help ensure your internal territory for later on. If you don't have an island to yourself you have two options, either take your neighbour out (this may sacrifice the beeline - go for Longbows instead if it does) and follow the above, or if you have more than one neighbour bribe them to fight each other. I wouldn't get too hung up on getting the Astronomy beeline in the fewest number of techs possible. The beeline is only of any use if you're actually around to make use of it, so if you need to get Longbows first, get Longbows first.
Four cities should be sufficient in the early game, perhaps drop it to 2-3 well placed cities and try to go taller than you normally would. Also consider taking Tradition (and particularly Monarchy) as well. Liberty is strong, but Monarchy with a strong pop capital can be a better choice, much better in some cases.
The economy problems are potentially more serious. Could you upload a save game or two? (I think this is done on the attachments section when you're posting - paperclip symbol along the top line.) Without more detail, it's hard to comment too much on this.
CS - These are situational. Don't purchase their friendship unless you have a reason to have them on your side: Cultural victory, strategically placed City State, needed luxuries/bonus etc.
Naval promotions - In short, yes. Against the AI taking anti-land is your best bet (although bear in mind this doesn't apply to attacks against Cities). Taking the anti-ship one would make more sense if the enemy floated more ships or in MP.
Victory choice - Once you've scouted your initial starting cities/neighbours you should decide how to win. Basic stuff but taking too long to decide between VCs can kill off your game. Sometimes VCs are decided by circumstances and there's little that can be done about that due to how the AI handles diplomacy.
