A few questions on renaming the admin folder

When renaming the admin folder, I'm changing these setting in configure.php in admin/includes:

define('DIR_WS_ADMIN', '/admin/');
define('DIR_WS_CATALOG', '/');
define('DIR_WS_HTTPS_ADMIN', '/admin/');
define('DIR_WS_HTTPS_CATALOG', '/');

define('DIR_FS_ADMIN', '/home/mystore.com/www/public/admin/');
define('DIR_FS_CATALOG', '/home/mystore.com/www/public/');

Now, say I want to rename the folder to abc123, are the following settings correct?

define('DIR_WS_ADMIN', '/abc123/');
define('DIR_WS_CATALOG', '/');
define('DIR_WS_HTTPS_ADMIN', '/abc123/');
define('DIR_WS_HTTPS_CATALOG', '/');

define('DIR_FS_ADMIN', '/home/mystore.com/www/public/abc123/');
define('DIR_FS_CATALOG', '/home/mystore.com/www/public/');

I'm not sure what to do about the 3 defines with just "/" at the end. Does it get changed also to abc123?

The ones you listed should be enough. That's what I changed when I renamed the admin.
