Monitor your oil loss but my understanding is it has further to go.  Mine started to weep and I managed to drive several hundred km's with no change.  Your's is a lot worse.
The Vac pump is located at the top front passenger's side of the engine (where all the oil originates) and is bolted down on to a flat bracket.  From memory it's the top pulley on that side too.  From what I've read it actually only loses about 50mL of oil, but makes a BIG mess.
As for the pump itself the service bulletin refers to only changing if it goes or shows signs of going.  From what I've read and speaker to others it seems to be more of a case of leave it and se if it fails as not all units do.  I must admit I thought by 09 they were all on the latest iteration of the pump but obviously that's not the case.
This thread of mine on Defender2.net may give you some degree of comfort: http://www.defender2.net/forum/topic...ht=vacuum+pump
But I'd still get it to the dealer soon.
