AC will be listed on the defense tab. It should have its own dialog window for accepting values for calculating the following:
Total = 10 + Armor bonus + Shield bonus + Dex modifier + Size modifier + Natural armor + Deflection modifier + Misc modifier
Also implement touch armor class, which is used versus touch based attacks.
"When you are the target of a touch attack, your AC doesn’t include any armor bonus, shield bonus, or natural armor bonus." This will be displayed as well, but only needs information from the above to be calculated.
Flat footed:
"A character who has not yet acted during a combat is flat-footed, not yet reacting normally to the situation. A flat-footed character loses his Dexterity bonus to AC (if any) and cannot make attacks of opportunity."
