Overall i would say it depends on how many character each person creates ~ i try not to put a limit on things until i know how intrested people are and such

The architecture For the Lycan's and Ursine would be quite Nordic in the design (Viking) so built to last at the same time ornate with carvings and sculptures 
whereas the Cattus theirs would be quite British medieval so quick to put up but not the most beautiful to look at and not as strong being a bit dumber 
level of tech will vary slightly from Kingdom to kingdom but again in general mostly medieval so swords axes bows with the newest tech so to speak being Cannons (though not many are built) 
Trade would be either be by boat down rivers or around the coast or via land by use of Horse n cart or shifting into their type to draw the cart 

As to address the second question: i would say its about a 80/20 split Being that when they shift they take on a lot of the characteristics of the animal they shift intohowever they retain enough control as not to attack allied clans (if the alliances reform) and humans who have not shifted (though accidents can happen!) 

If/when this gets to a proper OOC i will explain all this in greater detail 

as for when the OOC will be up will depend on how quickly i can write everything up and get my fellow Gm to proof read and add anything they wish and sort out any grammatical mistakes i may of made
