18" is the sweet spot. 17" if you find a set of wheels you really love, I guess.

I prefer the staggered M-Sport setup. Largest benefit from running a squared setup is prolonging the life of the tires, being able to rotate them with ease and frequency.

Not necessarily, depends on tire pressures you are running etc, you should just stay with stock sidewall ratio specs, relative to whatever width you run.

Not really. Larger tires are only beneficial if you are frequently running into traction issues during acceleration or cornering.

Yes. Narrower tires will result is a dartier, sharper 'feel'. However like I previously said, you should probably just go with the E90 M-Sport specs. 225 in the front and 255 in the rear.
