You have some old program versions there! Joomla!, PHP and Admin Tools are all end of live and unsupported. That's dangerous.
Admin Tools blocked the attack, it is not necessary to block the IP as well. Hackers don't use their own IP addresses, so permanently blocking an IP is of questionable use. Eventually you will end up blocking legitimate users. The auto-ban feature will ban the IP for a certain period of time, then release it. This might be a better choice. It will block the hacker from using that IP to attack you long enough for him to get bored and move on, but will not permanently block the IP address.
