That takes a little while so if your extremely paranoid you can change your key daily, rotate them. Something that I do that helps is that I have my wireless router outside of my LAN so none of my internal servers are accesible from the wifi network (except from the same means that they are accessible to the rest of the internet).
Id oubt he has an essid... That is the ssid on an ESS: more than one AP linked together. If he has only one AP then it's a BSSID :p

As well, AirSnort requires approximately 5-10 million encrypted packets to be gathered. Once enough packets have been gathered, AirSnort can guess the encryption password in under a second.
