You can define different layers of clothing. When an item of clothing has the same layer number than another one, they replace each other. I don't have access to my system with iClone and CC at this time, so I can't provide you with screenshots of the settings. But if you assign e.g. the shirt and change its layer number, you should be able to add the coat.
Correct. It's a setting under Modify called "Cloth Layer Settings".
