You are exactly right about form. Nothing is more critical shooting a bow than form and consistancy. I strive to, once I have drawn the bow, to let absolutely nothing move except my fingers as I release. The hand holding the bow doesn't drop till after the arrow has left and only the fingers holding the string move to release.
I personaly use finger tabs, no mechanical release. However if I ever upgrade my bow to something with a much higher pull wieght, I will use a mechanical as it makes it easier to draw, with the release wrapped around your wrist you can pull with your whole arm instead of the wieght on your finger tips.
The most important thing is to be consistant and enjoy it, don't make a chore!

The two enemies of the people are criminals and government, so let us tie the second down with the chains of the Constitution so the second will not become the legalized version of the first. Thomas Jefferson
