You can accomplish item #1 below using the GetPointCells method on the 
output of your Delaunay triangulation filter (vtkPolyData for 
vtkDelaunay2D, vtkUnstructuredGrid for vtkDelaunay3D).

You could probably use vtkExtractEdges filter 
(http://www.vtk.org/doc/nightly/html/classvtkExtractEdges.html) as part 
of a solution for item #2.
