When I watch the taking turns screen, I often see a progression of enemy agents appear from nowhere, enter a city and stir up civil unrest. Some cities are maxxed out on happiness/law bonux buildings, have a govenor that isn't too venal, a garrison (not too big of course) and a coterie of all three types of agents, yet are constantly suceptible to enemy agent attack. How do I stop this, and for that matter, how do I do it back?

To stop this , simply put one of your own spies in that city, that way each turn you'll have an X % chance at discovering him - and killing him.
Also , if you see the enemy agent, kill it with an assasin, spies are not hard to kill.
Enemy assasins even less hard to kill.

And as far as I can tell, number of troops and or governor also makes it harder for enemy agents to infiltrate ( spies that is )

As for your other Q's.

Come back to those later
