Sounds good so far.
Use silicone or furniture polish on the shafts to make them easier to remove but they will go into the target a bit deeper. If the arrows burry as deep as the flethchings I would get a different target or shoot from furhter away.
I agree with your comments about the rings but they work if you don't over tighten them. After having said that I've stripped everyone I've laid my hands on. I use Weaver detachable on all my scopes except my Freedom Arms.
You made a great choice, have fun!
