I just realized that the OP ordered DCT. I have not seen any shift boots for DCT yet. It is not like the manual transmission and the rest of the 3 series. Maybe the M5/M6 SMG boot is the same. But if not I'm sure one in other types of leather will become available soon enough. As for the shift knob you probably wouldn't want to change it. And if you did you'd lose the light up feature.
I've been assimilated. 6MT/ZPP/18"/PS extended.
