This starting location was a builder's dream

A continent all to ourselves, but with AI's in galley range for tech trading. As a builder, I thoroughly enjoyed it. This was my first ever XOTM and first time playing Emperor, so I decided to go with adventurer, as I knew I would make a lot of mistakes in forming my strategy.
Settled 1 SE to get all 3 food resources in Paris. Settled Orleans E to get marble and gold, but turned out to be just out of range of iron. By 500AD, i think I ended up with 5 cities on home continent, 2 on eastern islands, and 2 on the mainland.
Like ngraner and Jimmy, wonders are often my source of immediate gratification in this game. As such, before 500AD I had stonehenge, colossus, great lighthouse, parthenon, shwedagon paya, and sistine chapel in Paris and great library in Orleans. Stonehenge came in amazingly handy for taking the north shore of the mainland from barbs and for blocking Khan's expansion. I was using the pyramids as a wonder bank in one of my marginal cities for a long time, and when I finally realized at like 300AD that nobody had built them yet (did this happend to anyone else?), I started building it for real but got scooped by Frederick in 355. In retrospect, pyramids would have been really helpful for the strategy I chose later.
That strategy is also the reason I lost the tech lead. I realized slightly before 500AD that a cultural victory was my fastest shot. I never even considered conquest and domination (I don't have enough time), religious was a long shot since I didn't get hinduism till late (I guess that's a disadvantage of starting on an island...), diplomatic would have required a lot more conquest than I was up for, and I didn't have enough production cities for space. So around 300AD I decided to follow a modified-Godotnut cultural strategy, minus the pyramids (doh!) I can't say much more about it because most of it took place post-500, but if you are familiar with the strategy you know why I lost the tech lead. (be warned: reading
Godotnut's guide will pretty much tell you how I played the 2nd half of the game, but it obviously contains no spoilers about this particular game)
Things I'm happy with:
-I cottaged more aggressively than I ever have, and I was surprised how well it paid off without hurting my wonder production. Go industrious!
-I learned in this game how to effectively use whipping and chopping, two features I had previously ignored because they felt vaguely wrong (you expect me to wantonly sacrifice people AND cut down trees?!?!

) That's what I get for injecting morality into a computer game. Don't even talk to me about

s
-I actually chose a strategy before the endgame. Usually I just play for fun, bouncing from mini-goal (build that wonder) to mini-goal (take that guy's capital) until the "100 turns left!" comes up and tells me to get off my butt and start winning.
Things I'd change:
-Basically, take everything I learned and apply it further: cottage more aggressively (for a peaceful strategy), whip/chop more effectively, and choose a strategy earlier.
-Actually choose a state religion. I decided not to have one because the AIs were evenly split between buddhism and hinduism and I didn't have nearly the military to defend against any invasion. This decision worked out ok because I built the shwedagon paya and ran free religion starting in 310, but I can't always count on that in the future.
What are your opinions on this situation? If you're a builder with minimal defense stuck between 2 dominant world religions, do you convert or remain neutral?
How did the religious scene shake up in everyone's games?
For me, buddhism: Frederick, Joao, and Peter and hinduism: Pericles, Hammurabi, and Khan. The buddhists were more powerful, but the hindus were my 2 neighbors
Also, Erkon, have you picked a strategy yet if you're not going conquest/domination?
