I hope I didn't totally miss the point and give you wayy too simple of
answers, but here goes:

1) There is a SetName function in vtkAbstractArray (which
vtkDoubleArray, vtkStringArray, etc) are derived from. If I understood
you correctly, you can simply do

yourArray->SetName("text");

2) I don't think there is any "mass cast" like this. It should be too
bad to loop through the array and cast each member individually and
add it to the other type of array.

Hope that helps,

David
