Camber and toe-in are all you have to adjust. The beam is welded in the front so no caster adjustment. The rear has no caster either.
The number of threads exposed means nothing, the total length(axle to pivot) is what matters.
A computer setup isn't needed, you need a toe gauge(tape measure) and a camber gauge(which could be a construction square and a tape measure) and a flat floor. You could also use a 2 foot straight edge and a cheap digital angle gauge.
