So I basically have 2 questions:

1) Are BMW engines somewhat broken in already in the factories?

2) Since I've only heard about breaking in a car recently, I think I may have "pushed" my car a little harder than I was supposed to in its first 300 miles or so, with possible, brief instances of going over 4500 rpm. Has there already been damage or is it not too late to let it heal?

Sorry if these questions sound noobish, I'm kind of new to all this haha.

Don't over think it, and check out your vehicles manual, it has a section on breaking in the engine. It is on page 156ish under Driving Tips.

You didn't do any harm to your car, everything will be okay, she can take it.
