3)  While at Mud Volcano, I overheard a ranger discussing how the water there 
was much newer than the water at Old Faithful, indicating that the Mud 
Volcano water was only a few years old, while O.F. is closer to hundreds.  Has 
anyone else heard this (not that I doubt it), and is anyone aware of what the 
geology is behind the difference?

Quite simple, really. To generalize, in mud pot areas, although there 
certainly is some "old," that is, deep geothermal water involved, most of the fluid 
is near-surface meteoric water. This is why mud pots tend to dry out (at least 
to some extent, sometimes thoroughly) as the dry summer season progresses. So 
indeed, some water at Mud Volcano is in fact "brand new, 2004 water."
