I think paper tuning can help but I, personally, haven't had much luck with it and just tune it by repeated shooting and adjusting. I first tune it to the field tips then put on fixed blades for more tuning if needed until I get them both grouping. Easton's tuning guide is a good place to start. You may be better taking it to the pro shop, depending how good they are. I have some decent shops around here but it never seems like they can tune my bow correctly. Its not a bad thing to go ahead and start figuring out how to tune it yourself. You may be happier in the long run.
