I ran into a similar problem a few weeks back with vtkStructuredGrid.

For the issue of a vtkUnstructuredGrid... I'll try to summarize what I
said in [http://public.kitware.com/pipermail/vtkusers/2005-July/080704.html]:

I stored 3-d chunks of connected points with an unstructured grid. 
Every volume of space in my data was stored as a vtkVoxel cell.  Since
each cell is unstructured, it doesn't matter where you set it up in
vtk as long as you have your 8 indices (to a points list) correct for
each voxel.

I had no luck with vtkMergePoints either. 

Let me know if that helps you get started
