Civilization IV has finally become available in Asia. Thank God! Started playing the other day.

I noticed that a worker has more options available to him. I always select automated mode. Would the worker automatically create farms, and workshops? Or do I have make him build those?
Also, conquest by cultural expansion - does that happen in this game?
I do wish that religion had a more impact - kinda like what they had in medieval total war.
