"What is the best method of adjusting toe-in at home?

Fix the steering to be sitting straight up first. Then use a long straight edge (or eyeball it) to align the sidewalls of the front tires with the rear tire. The front and rear track width is near enough to the same on the MGA, so this will give you very close to zero toe in. Do this with full weight on the suspension. Also roll the car to turn the wheels 1/2 turn and check again, just on case there may be some aberration in the sidewalls of the tires.

A tiny bit of additional toe in will make the steering slightly more responsive. A little bit of toe out will give slightly higher cornering force (not that you would notice much) at the expensive of a slightly mushy feel to the steering running in a straight line. Up to 1/4 degree either way will likely not cause any noticeable increase of wear on the tires. That 1/4 degree at the front wheel makes for about 3/8 inch misalignment of a straight edge at the rear tire, so this method is pretty accurate, assuming the front tire sidewalls are running true. It could be made even more accurate if you use a parallel spacer at the front wheel rim to use the straight edge on the wheel rather than on the tire.
