Could you expand on what you mean by "see the IDs used for certain properties"?
Your code fragment above is incorrect. One of the keys to understanding VbScript and this API is understanding what is an object (when Set is required) and what is a simple property. In your example you are also missing the the step of getting the Layout property, which contains SelectionStyle. So a working example may look like:
set LB = ActiveDocument.GetSheetObject("LB01")
set box=LB.GetProperties
style = box.Layout.SelectionStyle
msgbox(style)
