Now I know that some of these items are a bit pricey, but for me it was worth it.
When I came to do the job it turned out that the lower pipe for the thermostat (LR050855 Lower Hose $106.16) and the thermostat had recently been replaced, some time prior to me purchasing the vehicle, so I didn't change them this time. Also the throttle body gasket isn't essential but mine was a bit battered and I changed it out, they are reusable.
The clips (LR011221 Clip $4.56) that hold one of the hoses under the supercharger body turned into dust as soon as I touched them so make sure you have these on hand, and they're not necessarily a stock item.
Hope it helps, Also not all of the supercharger belts are created equal, LR changed the crank pulley at some point I believe so check that one against the vin at your friendly dealer.
