JSeward,
the requirements for this stuff should be spelled out to you during your training as part of gaining the rating.
If not, then I would be highly questionable of the training you are recieving...the fact you asked here highlighted a flag for me.
An N-VFR rating is easy to obtain, difficult to maintain, let alone master.I often find I have an instructor along for the ride due currency.
NVFR is possibly harder than IFR, definatley one of the more challenging ratings that MUST be respected!
Enjoy
