All I do is find center where the ridge board will rest then get your plane lines for the sleeper and ridge, the sleeper is what the rafters need to rest on as well as the ridge board. then pull your layout (i usually tac a nail at each mark on the sleepers to pull my measurement from to the ridge). Then you may or maynot need to coller tie the rafters.

Hope that helps -will.

I'm in the same situation, but the response to this thread doesn't help me remember hoe to find the correct angled cuts for the jack rafters. If anyone can help me this, that would be great.

I'm not sure just what you need, but the jacks level (long) cut is the same as the addition pitch, with the degree of the main roof pitch.

Pretty simple to find the angles. Existing roof pitch is your bevel. New roof pitch back cut or simply 90 degrees subtracted by the pitch of your new roof.

Finding the "correct angle cuts" is easily done with a speed square. If you are familiar with the plumb cut, level cut and bevel it is all easy.
Say a 6/12 roof... the angle is 26.5*.... in your case it is laying on a 6/12 so its alll equal cuts. 26.5* plumb cut.... 63.5* level cut (90-26.5) and a 26.5* bevel. Using a speed square just be sure you are using the common scale for commons and the hip/val scale for well... the hips and valleys.
