religion gives you muuuuuch gold too... in my last game, i had 4 holy cities, and spread my religions on all nearby civilizations... i earned a lot. also, when spreading my official religon, i got to see on all the cityes of my future enemyes.
unluckly, i noticed that i was left behind. in late game, i found that indians got a couple techs before me, and they started to build spaceship. if that wasn't the end of the game, i could have just rushed settlers, but there was no time.... so i just nuked him to stop his project, while i used my supercity and some lesser cities to build space elevator and all spaceship parts... and then won 17 turns from the end, while being invaded by enemyes with bigger army. it was a big rush for your victor end.
so, while religions are nice, if you focus too much on them you might fall behind a bit in growth and research.
anyway, i suggest settling in 3, then if you want faster research go for gold, or if you want faster growth go for pigs and corn near spot 2. as errol said, you need a lot of cities. you won't regret that when you get ONU either.
in my opinion, any military beyond basic defense can wait till you see a war coming, or are worried about other civilizations.
that is all i can say, which could be wrong and isn't worth much, since i started playing again only yesterday, and i nearly lost at warlord difficulty.
