plainview

Took my wife's 2009 RX 350 93k on the clock, to the dealer yesterday for inspection and the report came back with a leaking water pump amongst a few other items but none as important. I've done some searching and have seen a lot of great information on water pump replacement but missed the part number for the water pump or recommendation on what water pump to use for replacement? Also what else should I have my mechanic replace while he's in there? Guess this could include items that are worn or items that might as well be replaced while he's in there to avoid a future job? I appreciate anyone's time to respond.
