I just thought of another fairly cheap thing you want to change, the coolant overflow cap.

Part no: 996 106 447 04

Very important that the part number ends in 04 (latest version). Part number may or may not be printed on the top of the cap. Check your current cap and if it doesn't end in 04 (or doesn't have a number on it), I would change it.

$28.18 from any Porsche dealer (they stock them) or Pelican, Suncoast etc.

Be careful when screwing on the new cap - its easy to get it on cockeyed and you'll start spewing coolant out the overflow hose if you don't get it on right.

Also, about coolant - I would only use the Porsche stuff. It seems expensive ($48/gallon) but it's full strength. When cut 50/50 with water it's really $24/Gallon, which is about the same or just slightly higher than buying a name brand like Prestone 50/50 at Walmart.
