Just to bring a little different perspective, as important as hardware may be, and you have lots of good recommendations, I'd advise spending a good deal of time finding a juice flavor she likes. You could use your REO as a dripper and have her sample several juices before deciding what she might like to vape. If she doesn't like what she's vaping she's never going to stick with it.
And the general disclaimer of you can't really force someone to stop smoking, only give them encouragement and support. You have some good ideas offered, and now you just have to see what will meet her lifestyle best.
