Toe Alignment Inches To Degree Conversion

Inverse sine of the half the toe (opposite side) over the wheel diameter (hypotenuse). So assume we want 1/8" total toe, that's 1/16" or .0625 per side. And assuming a 26" tire, Inv SIN .0625/26.00 =.138 degrees per side. As for being the same side to side, in an ideal world yes, but they're adjustable for a reason. A good alignment will split the toe about the a line perpendicular to and centered on the rear axle with the steering gearbox (not necessarily the wheel centered). This is sometimes called a "thrust angle alignment." This is also what you get if you just use strings and jack stands and set the strings off the back wheels. Hopefully, the body centerline is pretty close to the rear axle centerline, but you are concerned about what direction the wheels point and not the body. In your printout above, the rotational axis of the front wheels is not parallel to the axis of the rear wheels. Teh right rear is slightly behind the left rear. And you should be able to get more caster even with factory parts.
