SetInputArrayToProcess stuff is new to VTK 5.0. I don't know if it was
included in the VTK User's Guide. If not, it should eventually. I wish I had
time to write a collected wisdom book :-) It would probably contain more
about musical instruments than VTK though. There is also documentation in
doxygen. Look at vtkAlgorithm.

There seems to be. vtkPVArrayMenu has an attribute called
input_attribute_index that defaults to 0. It is not used anywhere but it
should work. You should be able to use 2 array menus with different
attribute indices.
