[C2] New wheels and tires - alignment?

The alignment must be the answer - I assume you still need to do that. I just finished rebuilding my suspension stock - except for the Koni's. Fronts are set to middle setting and the rears were left on softest setting. My specs are, Front camber -1.5, Caster +3.0 on both sides, and toe in is 1/32 total. Rear Camber is -0.5 and toe in is 3/32 total. I have power steering with the tie rods connected to the "fast" steering locations (Steering rods on the hubs have two holes - one fast one slow). I also went through the steering column and am using the "rag" coupler. The tires are 215/70R 15s on the knock-off aluminum wheels. The steering is a bit light, but my opinion, the car drives beautifully and will travel a straight stable path at speeds well over the 3 digit mark.
I did have one thought about the Rag coupler between the steering shaft and the steering box. I believe it is to allow for mis-alignment. If the rag coupler is removed in favor of something with less or no flex, I would think the alignment would need to be perfect, other wise there would be some binding which would cause the steering to "notchy" and cause interesting effects as the system tries to rotate the wheel to the location of lowest "bind" tension?

But I don't doubt it. If the car was driven for many hears, I can see that happening.

Update on alignment - I'm pissed because I lost the before and after print outs. I want to get them and will share. They are exactly Duke's recommendation.
Holy Schmoley Bajoly. It's a different car now. I swear I can feel those big ol' meats and it handles great.
Turns out, it was way out whack. Not sure if it shifted over time or if whomever did it last was an idiot. Or a chimpanzee.
