I agree with Mike on the timeline. You could cut some of that labor out though if you are at all handy.
I would ask how they plan to change the fluid in the transmission. We generally recommend a pan drop and filter change. You get quite a bit of fluid that way and don't disrupt anything in the transmission. This is actually an easy job, the hardest part is getting that dang filter out and learning to just leave the filter ring alone if it'* really stuck in there.
Supercharger oil is a snap to check as well and should be changed fairly regularly. You can use Mobil 1 Full Synthetic 5w30 in the SC, I would recommend sucking the fluid out through the fill hole using a small hand pump or turkey baster contraption, then refilling.
Air filter, easy stuff.
Rear Window regulators can be tricky. Need to make sure to properly reseal the water covers inside the doors otherwise you will get water on the floor in the back.
