I think this is where it becomes personal preference.

As of right now, my f30 is stock except for some awesome window tint.

But in the coming weeks, I will be wrapping my roof. Now normally, I would be against this, but I need to a roof rack to mount my road bike. And I don't want all the dirt and debris to damage my roof. Now, I am planning on getting carbon fiber roof (some don't like this route, and some do). The 2 other options that I was gonna go with were gloss black or clear.

For the spoiler, I would either color match or get carbon fiber. I don't think it really matters if it's M Performance or replica. Maybe others would like to chime in if they're shaped or molded differently.

The badge---again something I normally am against, but I am almost close to convincing myself to debadge (I have a 335i). It'd be nice to see a carbon fiber badge on a car though. But other than that, keep it OEM.

Now these are all my preferences, again, everyone has different flavors. Hope the best to you and your f30!
