I would actually suggest a different path. The most annoying thing you could do to the others is build the ToA. That way you have cultural borders that they won't, plus they can't keep any of your towns.
Other than that suggestion, Pyramids is good, so is Sun Tzu. If you can trick people into selling you techs, definitely Sun Tzu is the way to go.
Pyramids is the "safe" play, but with the other players you have in this game, safe just means you will get double teamed later on.
