Hahaha. Why did you rotate the one pic that would give the biggest clue (bottom right)? But I'd still refer you back to my previous post .. the edges of the wrong bit of texture are straight, so clearly those polys are in the wrong group. Do the coloured, labelled map export, as suggested, and I bet everything becomes clear. As for groups, you should be splitting the model into a number of separate groups and mapping them according to the topography of the parts. The cups, for instance, should be using the spherical mapping option. The straps .. planar. The back probably planar too. You might need to put in seams for where the edges of the maps meet, but you'll get rid of that stretching.
