: what are the benefits of smooth triangles?
This should be obvious when you see a mesh rendered with regular triangles
and then with smooth triangles.
For examples, see:

: do they have explicit
: normals in the file?
Yes.
Although the mesh smoother calculates single normals for each vertex,
it's perfectly possible that in a pov mesh there could be different normals
for the same vertex, one for each triangle (actually there is, but they
are often the same vector, but they could be different).
