You have an ear for sound. That's obvious. Especially the first piece with the spoken words at the front. It's a powerful way to start something and you clearly have a feel for it. "Seven Souls" (maybe you already know it?)http://www.youtube.com/watch?v=SQc3T45pRWY
is one of the great pieces in this genre. Which isn't to say it's a model for you.
Something to consider is the piano, unlike music production technology, isn't really a project for self-learning. I mean you could self-learn on it ... but it's usually not as simple. The other thing about the piano and acoustic instruments in general is they don't lend themselves all that well to a learning that only wants to get so much out of them in a circumscribed way ("I want to know this but not that").
If you're really interested in the piano get yourself a good teacher and go to it with the obsessive energy you mention in your post. Don't worry about what you want to know or what you don't want to know. Just learn about the piano. At some later point you can always choice to specialise in "this" or "that." But the beginning isn't the time for that.
In an idea world, a piano teacher who's sympathetic to your interests in electronic sound would probably be a great match for you. Because that's someone who can help you to transfer the strengths you already have to the world of piano that you now want to enter.
You gotta work with the right people to get the right results ....
Hope this helps.
