Jaff, there's nothing particularly unique with how the tires/wheels work on the Model S compared to any other car. Not really any different than a tire shop who's worked on Toyotas working on a Honda for the first time.
The only thing you need to be careful about are the lifting points when hoisting the car up, but they're pretty obvious to anyone who's worked on cars, and lifting points can be critical on many ICE cars too.
What I have done is printed out the Jacking and Lifting page from the Owners Manual (you can get the pdf at the Tesla site) and laminated it. I keep it in the glove box and leave it on the seat whenever I go in to a non-Tesla shop (so far, just Kal Tire for me). When I got my snow tires back in 2013, mine was the first Tesla my local Kal Tire had worked on. With the instructions I gave, they had no problems whatsoever with the car, although I did keep a sharp eye out while I waited!
I also keep a laminated copy of the Towing Instructions in case I ever need a non-Tesla tow (flatbed).
