In regards to your second question, I think that's why the holding-the-nose one works so well, because despite holding your nose shut, your real nose is still very much active and you can still breathe. The only way I can think of it not working, is if you imagined not being able to breathe - which I suppose would be pretty horrific, if nothing else.
Holding the nose and breathing definitely works the best for me, I've had the finger through the hand fail in a dream and even occasionally had a clock seem fine, but the nose pinch always works.
