What you are doing is comparing the width between the front of tire and rear. Using the razor blade is a good way to give yourself a good measuring point. Never thought of that one. I've done it with chalk, but that gives you alot of chance for error.
Basically you want the front measurement to be 1/32" narrower then the rear(tires toed-in) and as you drive it basically tires to pull them straight then. This will make them wear nice(no cupping from trying to scrub going down the road).
Yes, you need to make sure all is good up front, or it's useless because all effected components will cause tires to move around from your set point after you set truck down on tires again.
My '67 had 3/8" toe in when I bought it, but it had a camper on it and was squatted down and this was the way they set it up to not wear out tires. Since I drive empty for the most part I had to crank tires back out to get it to not tear up tires.

The first and most important thing is to have the correct camber with the normal weight the truck will be driven. This will require a shop that "knows how to bend beams". Loose king pins, wheel bearings and steering linkage plus wheels out of balance will cup the front tires. Check or replace radius arm bushings. Got to go, back tonight.
