I have to remove the U-trap below a washbasin
drain, all PVC pipe installed about 1987 -- and
am unsure how much force to exert on the
nuts at both ends of the U-trap section. Would
these nuts have been cemented with some
sort of PVC solvent or just Teflon plumber's tape?

You might want to just change it out while your at it. They are amazingly
cheap. The new one should not take much more than hand tight.
