I'm new to panorama and have reviewed documentation and tested a few shots but have some questions:
Equipment:
Nodal Ninja MKiii
Canon20d - I know a dinosaur
Sigma fisheye 8MM
Autopano Giga
Mac OSX
-2,0+2 exposures
4 shots per Pano 0,90,180,270 (No zenith or Nadir)

Current Workflow:
Import 12 images to a group
create stacks of 3 exposures
I forget what the option was but I have it selected so that I create 360x180 instead of 360x166(approx)
detect
90% of the time stitching is perfect

3 Current question:
Should I be taking original images into Photoshop and merging.  When stitching needs manual intervention I have 12 images and I'm not sure how to manipulate the control points.  I think having 3 exposures for each image complicates the control point optimization.

I have reviewed the documentation and videos but still having trouble editing Panorama.  Are there any other sources available

Does someone have a recommended workflow they can share?

Thank you
Mike
