Again, just my opinion: Probably give a run thru on the major & minor chords, but don't focus on having all of them memorized. Make it only a part of the lesson. Run thru the major & minor chords at the beginning, then focus on the 3 chord special she's starting out with (avoiding those nasty bar chords until she builds strength). As she needs the rest of the chords, she'll get fluent with them (able to hold them well and change quickly, etc).

Make sure she as a cheat sheet with all the chords on it, though. She'll do what ever she's motivated to do, so helping make that easy with chord grids available to her would be a great idea. Maybe get her to draw out the fretboard and write on it all the natural notes. It's going to be important for her to visualize that difference between piano & guitar, which is that you can play the same note many places.

All of this depends a lot on what she wants to do and what type of music she wants to play. If she just wants to strum & play some songs, then you can almost eliminate theory. If she wants to play classical, then it's going to take a different approach.

Me, I just wanna play! So I take the theory in small doses and I get along just fine. :)
