I realized I never posted back on this one. I tried to do the toe in by making what I thought were small adjustments based on how the car went down the road and measurements using carpentry-type tools. Before a long trip late last year I got a real alignment done and was able to observe and talk to the mechanic doing the work. Turns out I wasn't far off, but my small adjustments were way too big compared to what the mechanic was doing - 1/16 rotation, I would guess. Anyway, what turned out to be out of alignment, was the pasenger side camber - and this was an eye-opener too - had replaced strut inserts and been meticulous about marking the position of the top nuts, but on the driver's side, I actually ended up having to replace the whole strut with a junk yard one and ended up partially obscuring my marking on that side. The unexpected bit here was that the driver's side camber was bang on and the passenger's side needed to be moved quite a bit. By the way, before the alignment, I was really not seeing any driveability issues or tire wear, but afterwards the car did steer better.
