Hi all,
I realize that amino generally refers to a nitrogen attached to methyl groups or hydrogens, and amido refers to a nitrogen attached to a carbonyl group. However, when a nitrogen is attached to a benzene ring and also to a carbonyl, could you interchangeably call it acetaminobenzene or acetaamidobenzene? What's the right name? When I look it up they seem to refer to the same molecule, but I'm not sure!
Thank you so much for your time!

My answer would be,

C6H5NH2  = aminobenzene (aniline)

C6H5NHCOCH3  =  N-acetylaminobenzene, which is benzene substituted with an            acetamido group.

but you should look up the IUPAC rules on nomenclature for a definitive ruling.
