Great stuff! cool pictures too, looks like they're doing the deed 8)
I would try if you can to take the bns out, but only if it's not too much trouble.
Don't add white spot cure to the tank, that is only for artificially raising fry to stop the eggs from fungussing. They don't fungus when with the parents because they keep aerated water constantly flowing over the eggs.
The eggs will hatch above 6, I don't know who told you this, but they're wrong (mine were in about 6.4)
If you can, leave a small light quite far way, only just showing the eggs lightly (just enough for her to see something coming), but if you don't have one, don't worry about it (they don't have lights in the wild to stop predators, so they'll figure something out).
Try not to do a water change until the fry are free swimming, as you wouldn't really want them stressing from a change in water parameters (if this occurs during your water changes, not sure).
If you get your fry free swimming, just ask more questions then reguarding feeding, water changes, etc. and don't forget frequent updates with PICS
