The 330 calipers and the M3 calipers use the same brake pad size, front and rear. I believe that the M3 comes with a more aggressive friction compound from the factory.

Agreed. The Stage 2 kit will be more than enough. Very wise choice to upgrade your brakes first before going with fi. Most people go the other way around. Let me know if I can help you out with a kit. It includes the front and rear Stoptech rotors, Axxis pads, Stoptech stainless steel brake lines, and 3 bottles of Motul high-performance brake fluid. Everything you need to upgrade your OEM brakes. Let me know if I can help you out with a quote.

Stoptech Stage II

Why would it be well worth it? What are you trying to accomplish?

Larger diameter caliper pistons would simply mean your brake pedal would get softer since you need to move more brake fluid to move them. It would have the exact same effect as getting a smaller diameter master cylinder.

Seriously, the only reason for larger brakes is to dissipate heat better. And since the M3 and 330 brakes are nearly identical, well, you aren't going to notice a difference.
