I agree with the FE. The FM is also nice and the F3 (which is a pro level camera) can be pretty inexpensive on Ebay. You may find one for anywhere between 150-300$. This is a classic camera which is built like a tank and sold for as much as 1000$ just 15 years ago. Since it's a pro model, it gives the user the possibility to change prims and focusing screens. It has mirror lock up which is a great deal for still life images. It's flash syncro is also much higher than the other models of the same era. These things might be chinese to you but as she evolves in her craft, they will reveal themselves as being incredibly useful.
In terms of the wide-angle versus a macro, a wide angle will get more use but with the lens that she already has, it already covers that since it starts at 18mm. Lenses below that tend to be pricy. I got a Sigma 10-20 (500$) which I love and comes close to a Nikon prime lens in terms of image quality.
What she has in terms of lens at the moment is a stock lens... they are ok but that's it. At certain focal lenghts and/or f stop, they can be a little blurry and the contrast may suffer as well. Basically, anything out the prime lens range can be unstable at one or many of a lens' image quality characteristics: sharpness, contrast, vigneting, colour rendition, f-stop balance, etc.
Since she loves portraiture, I would suggest you get her a good quality portrait lens. Something like the 85mm. The f1.8 is about 250-300$ and the legendary f1.4 is just under 1000$... but what a lens!
As for the macro lens, simply get her a set of extension tubes. I got a set on ebay (
http://cgi.ebay.com/Macro-Extension-...tem4a9ca218c4). Cost about 7 bucks and has 3 different sizes which are combinable. Make sure you get a set which is suitable for her Nikon model. No need for a seperate macro lens if you get her a good 85mm or even a 50mm. I have the 50mm 1.4 (Nikon) and the sharpness is unreal.
As you shop for this, you might fall on a old series E lens in a second hand shop. Avoid those at all cost. They are entry level lenses and can be very bad. If you are tempted by the cheaper Sigmas or Tamrons, do some research on sites such as dpreview.com beforehand. They can make very good lenses but there are some lemons amongst them.
I hope this helps.
