Toe angle to inch conversion: http://forums.hybridz.org/showthread.php?t=126700
If your alignment machine is a Hunter, you can choose to display in either format, you just have to select the inches in the right screen (I can't give any more detail than that as it's been 10 years since I did my last alignment).
Your rear is obviously off compared to the front. The negative toe value is toe out. Toe out in the rear is not good, especially with semi-trailing arm rear suspension. You could look into slotting the crossmember to get some adjustability back there to fix.
If I were you and everything were adjustable I'd try more toe in up front, like 1/8" total toe in, and more neg camber if you can get any, maybe -1 or -1.5 degree or so. Then work on the rear and try to match them up more or less to the front settings. 3/16" toe in out back works well on the semi-trailing arm setup, get rid of the squishy rubber bushings back there on the arms too. If you really want it to handle well, get rid of the subframe bushings that attach the crossmember to the chassis and replace with aluminum or poly. This stuff is all fairly common in the 510 world, you can look there for more answers too.
