They go hand in hand. If one is correct, the other will be also. If one is incorrect, so is the other.
I think the most important underlying aspect is your state of being. It isn't a matter of which foot is where, or whether they fall or not. It's whether you have control of yourself, how relaxed you truly are, whether or not your mind is clear, and so forth. In essence, it's a matter of your level of self-mastery. Gain that, and technique and form will come naturally.
At least, this is how I see it right now.
