The global variable $post is available by the time the 'template_include' hook fires.  Add this to your theme's functions.php file to see it in action:

add_filter( 'template_include', 'marios_template_include' );
function marios_template_include( $template_file ) {
  global $post;
  echo "Post ID: " . $post->ID . "</br>";
  return $template_file;
}

Hope this helps.
