Hmm, do you think Cole was ever in the field enough for it to matter? I guess he went out enough to get killed, so it isn't such a stretch to think he could have been made.

As for Shaw, if anyone ever called her Samantha rather than Sam, I haven't been able to find it in transcripts, although that doesn't rule out the possibility that it was shown in writing somewhere. IMDB does have her down as Samantha, but maybe they just assumed along with the rest of us?
