We noticed the oil quantity and pressure were declining on engine number 3 and did a precautionary engine shutdown.  We needed to descend (drift down) to FL330 and were not getting permission to do so on the radio.  We put a request through the ACARS and received clearance to do so.  We proceeded to divert to the nearest suitable field and landed uneventfully.
While in cruise flight at FL350; noticed number 3 engine oil pressure and quantity indicating amber. Followed AOM/QRH procedures as oil quantity dropped to '1' and pressure indicated 'red'/unsafe. With Captain's approval; followed QRH and performed in-flight engine shutdown.
A MD-11 flight crew reported shutting down number 3 engine in flight when the oil pressure and oil quantity dropped.
