Just that a firewall can't protect you from bruteforce attacks unless you block HTTP - blocking ports which aren't used is a little bit useless.
Other tools like fail2ban that scan logs for possible bruteforce attacks and block IP's can do a lot of damage - Logfile injection as example so you've a nice SelfDoS. Also, in a world of bot nets where private comps are abused blocking IP's usually hits the wrong people - the real attacker simply uses the next comp, another IP and continues.

Generally - check all files on your server and compare them with the original ones from trusted sources. Both the PHP files and the OS files.

Then changing Passwords may be useful - all this just in case some hidden backdoor has been installed
