Nice. I'd be tempted to go with the standard GTS suspension drop of 20mm rather than going back to the 10mm. I've got the 20mm on my GTS and have had the 10mm on a prior 718, and am very happy with the standard GTS configuration.
Think a number of people have been advised that LED lights are no longer available from plant.
I've had the dual zone heating on a couple of prior Boxsters and was disappointed that it was not on the 4.0L GTS I bought, but to be honest I don't miss it. I've found the standard set up is, whilst a bit more of a fiddle to use, gives you much more control over heat than the dual zone. In fact on the new GTS order I have in - since July 2021! - I've changed the order back to non dual.
Know it's a bit of a stretch, and have heard there are supply problems with them as well, but the 18 way seats are sooooooo comfortable!
