>>You'll have to put ( at least ) 6 mil plastic down,

If you put the thick plastic down you will trap the water between the
concrete and plastic, encouraging mold growth. If you use Styrofoam panels,
the moisture can get through eventually, unless you have standing water. 

You could also screw treated 1x2s to the back of the plywood before laying
it down without Styrofoam to keep the plywood off the moisture and allow
some air movement.

You'll have to put ( at least ) 6 mil plastic down,
then pour more concrete with the heating pipes in it,
OR, much better, plastic, rigid foam, heat tubes and
THEN concrete ( or wood ) floor.
     For a  "quick fix", put down thick plastic, and
plywood over it.( Or just cheap brown pressboard ).
