For validation purposes I always like to print the Form within the script
that is doing the validation.  It solves a lot of problems.  As for coming
back to the Form at a later date the method is going to depend on how long
you want to keep the data.  A Session will only last as long as the client
is active.  A Cookie can last a lot longer but they can always be deleted
and many users turn them off until they absolutely need them.  You might
consider a Login/Password system and store the user preferences in a
database for the most flexibility and control.

To store the $_POST vars in a the active session using strict methods you
can do something like this:
foreach ($_POST as $key => $val)
    $_SESSION[$key] = $val;
