Download Stu's Calculator, it's the best thing going for selecting arrows for trad bows.
Things you need:
Bow Stringer, as even the push-pull method risks a twisted limb.
Bow Square, absolute necessity for for checking/setting brace height and nock point.
Extra String, self explanatory.
Glove or Tab, don't go cheap and once you figure out what you like, buy an extra.
Arm Guard, get a good one. I like buffalo leather.
Practice arrow quiver, I like Dave's Hip Quiver by 3R.
Broadhead Quiver, (when you get ready to hunt) I like the versatility of a side or hip quiver, but there are times I use a bow quiver...
