The charts above are the go-to references for Mathews tuning, and I'll second the Gillingham videos as well.
A third but more esoteric resource is Jesse Broadwater's Vimeo series on tuning compound bows. It costs money, but shows him setting up a TRX target bow. Very good and applicable to hunting bows of course. The money spent was worth it to me, because I like video instruction, learned a little that I didn't already know, and felt good knowing that not every single thing in your setup has to be "to spec" -- meaning there's some wiggle room with your letoff, draw length, rest setting, etc. all for the purpose of a bow that holds great and shoots where you point.
