I believe you have done as much setting up as you can do in OpenStudio. It's just a basic air loop with the addition of the supply plenum before the zone diffuser. If you're trying to go into more detail than that the key for you is going to be defining RoomAirModelType object and RoomAirSettings:UnderFloorAirDistribution. Neither of which are supported explicitly supported in OpenStudio or accessible in the GUI for that matter. Those are the objects that will allow you to define your thermostat height, plume strength and such...In order to use those you'll have to manually add them to the idf for every zone or write an E+ measure.
Unless you have large thermal zones I don't think adding the room air model type is going to make that much of a difference though. The main source of heat transfer change for UFAD systems is the supply plenum and you can capture that without changing the room air model type. You don't have to trust me though, for all you know I could be a compulsive liar!
