One thing to be aware of, that I fell into, is getting overwhelmed and too deep into the technical side that it confuses you and drives you nuts. Honestly, do not worry about hitting anything to start out, focus on a grip, draw, anchor, release that you can repeat everytime. Jumping to some of the real fine detail tuning, while you are unable to actually repeat each shot exactly will drive you nuts.

Otherwise, lots of good info here, what really helped me were the Masters of the Barebows vids, especially #2.
