Yup, the skosh chart is pretty much the way to go. With tubular uppers you can probably get more positive caster than what's shown in the chart. If you have power steering shooting for +5° caster would be good. If you have manual steering you might not want quite that much, depends on the use of the car and tires you're running. But say -.5° camber, +3 to +5° caster, and about 1/16" toe in should work well for most street applications.
How did you set the length on the adjustable strut rods? Hopefully you cycled the suspension through its range of travel to make sure nothing was binding. The alignment shop most likely won't want anything to do with adjusting those.
