The following script will copy the settings for a selected font into the active document's settings. Do note that the information can only be retrieved for TrueType/OpenType fonts! It may be possible for other font types as well (Type 1 fonts, for example, may have this information in their – separate – AFM file) but I do not know how to retrieve that.
The TTF tables actually define more than you can use in InDesign: separate X and Y sizes (the script only uses the Y size), and both X and Y offsets (again, only Y is used). Oh - and you can change the values in the boxes before pressing OK.
