This last rule is actually not hard at all, since your viewfinder and LCD panel shows a manual exposure guide (in Nikon, the same bar that shows EV compensation).
If really want to learn the sunny 16 method, use a lens your camera cannot meter with - like a Ai/Ais lens on a D90/D80/D70/D60/D40(x)/D5k/D3k.
