Leathermang is correct. When radials first appeared on the scene, you had to keeo them on the same side of the car, because the belts took a set. Michelin was the pioneer in mfg a tire that could be swapped. Today all radials can be swapped side to side. Radials are superior to cross ply tires, because they don't build heat like the scissoring action of a cross ply. As far as alignments go, a good two wheel alignment on any machine including any good machine that is 30 years old will do the job. All the hype about the new technology is what is called smoke and mirrors. If you have a multilink suspension or car that has been in an accident, that is a DIFFERENT STORY.

Yes, you have a caster setting or you would have to drive your car like a kid's pedal car. Caster is what keeps the car tracking straight and returns the wheels on turns.
