Congrats on the order.
A) Get the comp package, i am sure 19's will be just fine! If your worried about it get EDC.
B) I dont have edc and ride is great. I am however getting coil overs for improved ride for road and track and have some adjust-ability.
C) Both are great, but i personally would do Space Grey - wont look as dirty in winter. But JzB looks amazing when clean!
D) Just say no to DCT! LOL - i think it has been resolved for the most part - i am sure if you search the forum you can get better answers. I test drove a DCT and its not for me. I much prefer the third pedal. I briefly considered it so the wife could drive it, if I bought an E93 I may have been more inclined as I am sure she would like to drive that from time to time.
Tough problems to have
