Spin-orbit does NOT ALWAYS break symmetry, and in many cases the procedure
works. I'm sorry that you had problems.

There is no "must". In fact for EFGs,.. you should not do so.
However, I would recommend to do, because it gives (for E-tot,..) more
accurate results because you have a better basis.

Yes, just take the E-params from in1c.
