For the bodywork question, I found these links in the HowTo section at the top.

There are a variety of different spoilers out there, but I went with the OEM unit from Infiniti for my M37x. I think I posted before and after pictures in here somewhere. You can get/order them color matched for your car. I got mine off of eBay, but in OEM box, with instructions, drilling templates, etc included. I had mine installed by local independent shop, but installation is a doable project for the handy (for the brave, for the careful).
