Need some input ASAP.
As for the stereo, PAC makes a kit for our cars enabling you to use the steering wheel buttons. I would get a stereo shop that knows what they're doing to mess with all that for you.
I have Bilstein shocks with Vogtland Springs and I love them both. I rub in the back only if I take a steep degree bump at a speed I shouldn't have; this is mostly on the outside of the tire too. I run #4 E Class pads in the rear since I have 130+ lbs. of subwoofers back there. That is the main reason I rub. If I didn't have that back there, I'm confident I could go #1 pads in the back and not rub.
