I think the Easton Tuning Guide is pretty good. From basics up to ultra-fine tuning. It covers most stuff. And in English.

As for manufacturers putting out data, a lot of them have technical data such as A2A and brace height, cam settings. This should be enough get bows to specs.

As for tuning, it's not necessary. Tuning is tuning and the process is pretty much the same for all bows, whether they are the "latest and greatest" or 30 years old. Your goal is still matching the bow/arrow combination to your shooting form. It's pretty basic stuff. Oh, there's always little things that matter, but the way technology changes and bows change it's a constant learning process. Once you have the basics you're set to go.
