Welcome back!

1. 10" is too much. I don''t know what bow it is, but I'd venture to say to keep it around 7 1/2-8 inches.
2. I don't think those arrows will work well, be careful. They will more then likely be too stiff. Unless you are using a raised rest, you will need feathers.
3. Get the book "Become the Arrow" by Byron.
4. Sounds good!
5. I am usually aiming the during the whole shot process. So I am usually ready to release when I am at anchor. I may pause, but that is about it. If I hold too long the rythm of the shot is gone and things start to break down.
