I want to be able to read every property from every object in a vi and write those properties to a text file. I am really not sure how to go about this as I don't understand how to dynamically access properties from a sub-class. Any ideas/help would be appreciated.

Take a look at the code in my Property Browser, available here. I have code that retrieves all of the readable properties of Front Panel, Block Diagram, and Project Explorer objects and displays them in a window. At least it gets you part of the way there by helping you get the values. For me, it needed to be really quick so that the user doesn't see much lag when selecting different objects. I accomplished this by having a VI for each object class in the VI Server (made via scripting) that has a property node with all readable properties. It gets ran dynamically with the object's reference passed to it and the all of the indicators values are read all at once after it executed. If I were trying to do what you are describing: I would get references to all objects, use the VIs I created and dynamically call and read the values in a loop on those references, and write that data to a file somehow.
