The extra cooling hardware is part of the PPK2, which is why you see the wheel off in that pic as that was being installed.
As for the stainless steel pedals, don't even get me started as I had a big fight/rant about this back in the day with my sales person and BMW, but seemingly only the manuals were coming with the stainless steel pedals, but not the DCTs, which didn't make a lot of sense. So, no DCTs came with them installed. I made such a stink though, they gave me the $100 pedals for free. I think they look much better on the manuals though as you have 3 nicely sized pedals compared to how they look with the DCT and the big fat brake pedal.
Here they are on mine though:
