a Refuah for someone, (or e.g., to obtain the healthy release of Gilad  
Shalit, etc), is such an arrangement valid and binding?  Such stories  
exist in Chasidic Literature...

This is something I have always found fascinating. It seems like a  
chutzpa to tell HaShem to take away your cheilek in O.H. If that's  
valid, then you might as well ask HaShem
to take away your cheilek in Gehinnom. The mere fact of asking HaShem  
to take away your cheilek in O.H. implies that you unequivocally  
deserve the cheilek to begin with.
That's where the chutzpa comes in. OTOH if you ask HaShem to take away  
your cheilek in Gehinnom, that is tefilla and shows how humble you are  
because you don't even
feel worthy of Gan Eden. Secondly, it would seem to me that a true  
Tzaddik would not make such a frivolous request. I believe the stories  
which exist in Chassidic literature are          parables and  
allegories.
