Why would you insulate between the duct and the floor? Seems
like it's good to have a warm floor.

If you use the basement at all, adding insulation to the
ducts is
going to make it appreciably cooler/colder and you may
regret adding
the insulation. Eiither method you propose should work, but
wrapping
the ducts means going between the ducts and the floor above
and that
may be awkward if the duct is close to the floor.
