You can't adjust your camber angle but you need to know what it is before you adjust your toe-in. Your camber angle was set when your axle was made. Usually 1 degree but there can be minor differences so you normally get a .5 degree +/- factor. If your camber measures differently on each side, have the shop rotate your wheels 45 degrees and check again. If the measurement is still off, swap front left and front right wheels and check again. As you already have figured out, camber is a small measurement (in degrees) but sensitive. If your camber measures .5 degrees, use the smallest toe-in measurement (1/8 in this case). If it measures 1.5 degrees then use the high end (7/32 in this case. If it is right on 1 degree, then use right in the middle of 1/8 and 7/32...11/64 if my quick math is ok. If your camber measures something like .8 degrees, you'll need to do some calculating.
If you want an easy view on what your camber might be, get a good 9 inch level, set it against the lips on your brake backing plates (behind the axle) hold it as vertical as possible and see where the bubble sets relative to the little line in the glass. It ought to be the same on both sides and usually is. A bent wheel will mess up some alignment machines...the ones that clip onto the rim of your wheel. Good luck!
