My us$.02:

Do not get dev stitching, car interior is bizzy enough without it. I don't get dev stitching either: is the car interior some western-cowboy-saddle-based reference to leather? They deviate it because they CAN deviate it? Sorry. Nix crest in headrest for same reason.

Some of the out-of-the-way leather bits are unnecessary because the "plastic" versions are incredibly leather-looking.

Painted seat backs: total waste in non-Cab. They NEVER get seen AND WORSE: you'll always go nuts trying not to scratch them by you or your passengers putting stuff back there. Keep in mind: if stuff touches the seat backs and you go for a long drive that stuff (like a zipper or snap) can wear away and mar the painted backs. Had them in my 997 C2S and now see them as a PITA wa$te.

BTW, IMHO, you should be driving this car in your socks. I do. It's much more comfortable and with my big feel I can feel smallish pedals muuuuch better.
