Ok, so I kind of figured it out. I went with these settings (the default during installation):

PHP Code:
  define('HTTP_SERVER''http://servername.net');
  
define('HTTPS_SERVER''https://servername.net');

  
// Use secure webserver for checkout procedure?
  
define('ENABLE_SSL''true');

// NOTE: be sure to leave the trailing '/' at the end of these lines if you make changes!
// * DIR_WS_* = Webserver directories (virtual/URL)
  // these paths are relative to top of your webspace ... (ie: under the public_html or httpdocs folder)
  
define('DIR_WS_CATALOG''/~aimaa/store/');
  
define('DIR_WS_HTTPS_CATALOG''/~aimaa/store/'); 
I find this strange because for my admin/includes/configure.php, I had to set my HTTPS server to servername.net/~aimaa. Weirdness. I guess I just don't understand directories all that much... and hope to never work with them again...
