Alignment finally done, but ?

Radial tires are so forgiving, that'll never hurt a thing. I prefer a little positive camber because it gives the car a better presentation than tires leanin in at the top. For just cruising around and the occasional blast down the strip, I'd say you're good.
For modern radial tires I agree to a point. I remember the fiasco with the early Firestone 500 steel belted radials (among others) that had belt migration problems. Regardless of what the book said to set the toe, we used 0 or 1/32" toe in to help keep those belts from coming out the sidewall. Having 1/2 degree of negative camber isn't even visually noticeable IMO, but helps in cornering and emergency handling.
