If you can, get the electrician to flip that outlet over. Tesla asks that the ground pin be at the top so that the cable will hang nicely. The way yours is installed, the cable will try to hang upwards, and may tend to pull the plug out.
There are a bunch of good suggestions around the forum on hooks and cable organizers. You'll want something to keep the cable off the floor and make it easy to reach. However, I suggest that you don't actually install that until you have the car and see exactly how much space you have and where the charge port ends up when parked.
Congrats!
