GetAttachmentStatus returns the OBJHANDLE of the attached vessel, if you ask it. OBJHANDLE can be turned into Vessel interface by oapiGetVesselInterface (Or so, I am not sure, and away from API docs, I work from my memory here).

The rest as described.

You can also query the default propellant resource, which is the resource displayed in Orbiters HUD.
