I also use a RPM camber guage that you can also use for the castor settngs as well. Just line it up against the kingpin and it'll tell you what caster setting you have. As for toe in/out, I set the steering so that the servo saver is in the central position and then use the marker lines on my HUDY setup board to get the wheels running at a very slight toe in or straight ahead. Seems an easy way to do it although NIFTECH make a very snazzy tool for setting the toe angle. Cheers.
