Have you done the calculations on what it costs to print with those printers compared to printing online with places like MPix where you can get a 16x20 for 15$ or so. Not to discourage you from printing your own but for me it's cheaper and easier to just order prints.
That depends on what she wants it for. If it's for making negatives for alt-process, then you pretty much have to do that in-house regardless of cost. If it's for printing happy snaps to give to the relatives, then any online print service will be much cheaper and faster (and more accurate until you get the hang of printing).
