Drying...
In the books by Arentz & James they discuss using various set-ups of hairdryers for drying Pt/Pd coated paper. James warns about ferric oxalate that becomes airborne during blow-drying and recommends wearing a mask during this part of the procedure. I personally do not want to give this toxic dust the opportunity to flutter about in my darkroom so I would like to air dry my paper, however, neither author even mentions the possibility. Am I missing something? Is the heat of the dryer intrinsic to the process or can the paper be put in racks for drying? When the paper is dry can it be stacked with interleaving or is this a potential source for contamination?

Humidity...
I have a psychrometer so I can measure the humidity of my darkroom. Just curious about the ideal humidity level and if others are recording this data as part of their documentation for each print... or is this considered to be waaaaaay too obsessive?
