As you guessed, this change will break elsewhere, but a modified version 
may be needed.  Exactly one of the following should be true:

   - sizeof(long) == 8
   - VTK_TYPE_INT64_NOT_STANDARD is defined

I suspect that the problem is that the type "long" is really 64-bit, but 
vtkIdType is defined to "long long", which is also 64-bit.  Since "long" 
provides the 64-bit type for vtkClientServerStream, it doesn't bother 
adding the "long long" overloads.  Then code that uses vtkIdType breaks. 
  I'll work on fixing this case soon.

Someone else will have to comment on your other two questions.
