Regarding point 2): Use x = sprintf( "%d", {SOMEVAL} ).

Right from the manual:

  SYNTAX:
  s = sprintf(st, x)

  DESCRIPTION:
  This is exactly the same as printf(), except that the output is
  returned as a sequence of characters, rather than being sent to a
  file or device. st is a format string, x is the value or sequence
  of values to be formatted. printf(fn, st, x) is equivalent to
  puts(fn, sprintf(st, x)).

  COMMENTS:
  Some typical uses of sprintf() are:

  1. Converting numbers to strings.
  2. Creating strings to pass to system().
  3. Creating formatted error messages that can be passed to a
  common error message handler.

  EXAMPLE:

  s = sprintf("%08d", 12345)
  -- s is "00012345"

  printf, value, sprint, get, system
