Answer 1

If I understand correctly, you are trying to deploy a content page (sample or pre-built page). It has an embedded resource but the resource is missing which is throwing a node constraint exception. AFAIK and nt:resource node needs content binary data.
Can you check if your package filter is picking up the image/binary files for this path? The package has changed between 6.0 and 6.2
