A little late to the party, sorry, but I also do my own wheel alignments.
I have self-made laser gauges which make the job easier and quicker, but there is nothing at all wrong with string, rulers and camber gauges.

To second what @m3bs said, if you touch the camber, you more or less must check the toe in.
It could be off by quite a lot.

As for SAS reset, I have found it to be a mixed bag.
If you are very careful when making your toe adjustments so that the wheels are equally toed along the axis of the car with the steering wheel centered, you will probably be OK.
I use another self-made laser tool and ruled placards to check that.

However now and then if all else seems right and the steering wheel is centered when traveling dead ahead I will reset the SAS just for form.
I have an Autel "MaxDiag" MD808 Pro scanner that does it with a button click.
One of the best tool purchases I have made in years.
