An MD80's oil quantity decreased in flight with oil pressure and temperature remaining normal. Later; however the temperature rose and the pressure dropped so the flight crew shut the engine down as per the QRH; declared an emergency and diverted to a nearby airport.

Narrative:
Approximately 160 NM out of diversionary airport at FL360; the right engine oil quantity slowly went to zero. The captain and myself had already gone through the QRH oil quantity decreasing checklist. The checklist had us watching for decreasing oil pressure or increasing oil temperature. Neither occurred and we continued the flight per QRH procedures; figuring the problem was an inoperative oil quantity gauge. Several minutes later the right engine oil pressure dropped rapidly and the oil temperature rose. We continued into the QRH engine failure and shutdown checklist; and secured the right engine before any damage could be done to the engine. We declared an emergency and diverted to the nearest suitable airport for an uneventful descent; approach; and landing uneventful.
