Yes ! brass knock's and shrink tubing are the item's needed for this ,the manual tells you exactly where to put them on your new string .I'll be doing this as well in a few week's ,as for adjusting them I'm not aware of this but you'll be able to find this out when you put them on. Chrony it before you put the new string on and then again after ,if the speed isn't at least close then move them up an 1/8 and then again 1/8 lower than at first ,where ever you get the optimum speed then that's where you'll leave them.
