need4speed and others - a question about security.

my home is set up with 802.11g wifi. i currently have enabled the following security features:

1. MAC filtering
2. WEP encryption (i heard this sucks)
3. non-broadcasting SSID

should i be doing anything else to increase security? yes, i know that if i want real security, i should use a wired network...but wireless is too damn convenient

(PK, sorry for the thread hijack, but i think you'd probably want to know the answer too) ;)
