Security Tools Galore

I'm working on recording a security video series right now and came across this link: http://www.insecure.org/tools.html. Can we say ROCK ON?!? This is a list of the top 75 security tools you can use to audit your network. This is guarentees at least two months of tinkering around with these widgets. My top 5 are:
#1 Ethereal (the ol' standby)
#2 Nessus (be your own auditing company)
#3 NMap (port scanning galore)
#4 Netcat (port redirection & general hacking widget)
#5 Snort (free IDS)
