 * If I edit wp-config.php for an existing installation (e.g., to define(‘WP_CACHE’,
   true)) how do I apply those changes? Does just overwriting the existing wp-config.
   php magically make those changes take effect?

 * yes, that does it, because all the wp-files use the config file, a change in 
   the config file takes effect right away,
