She wants to learn photography and eventually to develop? If it’d been only the first then I would have asked whether she wants to become good on a dSLR or learn more about the nuances of light, etc. (not mutually exclusive, I understand, but follow me). I think anyone taking on a student now has to focus first on the end product desired - to master the digital auto thing (then skip right to the dSLR and work on mastering settings, white balance, etc.) or to be able to produce great negatives.
Sounds like she’s interested in a film foundation. So I would recommend the M3 and a 50mm. No bells/whistles and no help from anything. My M3 has brought me a long way recently and I've been shooting for quite a while. There's nothing like the "sink or swim" of a fully manual camera without meter. And a 50mm prevents the shotgun approach to composition that can result from something wider to start.
Oh, and on the argument that a dSLR provides for better learning via instant feedback, I think it also breeds a "disposable image" attitude in some that will not focus the shot decision making. We’re back to the initial question of the final goal. If it’s to be digital then she should learn to operate well in that environment. But if not, she'll probably think a lot more about what she's doing with an M3.
