The key the music is in has little bearing on how you should approach EQ.
You're going to have frequencies spanning the entire frequency spectrum
regardless of what key the music is in. You should first determine what type of
sound you are trying to achieve and then use the EQ to correct or enhance to
achieve the desired effect.

There are no formulas, and no one can give an opinion without hearing the
music before and after compression. Again, it's all about what you want it to
sound like. You need to be able to listen to the original piece, and be able
to say, ok here's where we are, but this is where I want to go with it. And
then make changes accordingly.

Train your ear. (Takes lots of practice) If you can't determine the frequency
very well by ear, take a single pole filter with a tight Q, and sweep the
frequency range during playback. You'll know when you hit the frequency you're
looking for. ;)

If you can't hear it, it doesn't matter. Don't risk compromising the audio by
applying filters you don't need. (I doubt you have any mics that can pick up
anything in those frequency ranges anyway)

Yes. Higher sampling rates matter when doing digital processing in the
frequency domain. Higher bit rates help with dynamics processing.
