Sure, welcome both of you to Team Sirius!
Generally in Civ4 you have to take the start you get and work from there. You can't really apply a general strategy plan to every single game, because every game is different - different resources around you, different lay of the land, different neighbours, and distances between neighbours vary too, amongst other things. Plus of course, not every leader should be played the same way.
Although building Workers and Settlers early on is always a good idea, so I expect we'll be doing some of that regardless.
We'll make all kinds of agreements as the game progresses, I'm sure. These games are known for their heavy diplomatic element, so no doubt we (and all the other teams) will be negotiating deals at some stage.
By the way, you can make a signature by going to "My Account" (near the top left of the page), then clicking "Edit Signature". Then you don't need to write in your signature manually with every post.
