Either bare shaft tune or paper tune. Don't combine the two. You'll wind up in a padded cell if you keep trying that.

Back up to square one. Set your tiller even on both limbs. Set your rest height to put the arrow in the center of the rest mounting hole. Get a pair of small, smooth jawed needlenose pliers to loosen the top knot in your loop. Jewelers pliers are ideal, and you can get them at any hobby store. Then you can adjust your nocking point.

The only adjustment you need to make to your tiller is to make sure you have tension in each limb matched to your grip style, as BPS noted.
