early game expansion tactics

That is a loaded question Andy .

I can only say a few things that will help you with the advise you may soon be recieving.

Post your Pretender and Paths.
Post your Nation/Theme.
Post your Scales.
Post your Dominion/Castle.
Post your Research goals.

All of these impact greatly your early expansion with the choices you make for it both in magic and production.
