Foundstone always puts together great research and releases great tools.

The other day Foundstone released a whitepaper describing all of the new and old 802.11 (Wireless) attacks. The paper gives some really good information about AP Impersonation, Rogue Access Points, Implementation Attacks (WEP, Dynamic WEP, WPA/WPA-2 cracking, including the Cafe Latte attack). The paper even goes into wireless client adapters and wireless DoS attacks.

If you conduct wireless penetration tests or want to know more about wireless security, I highly recommend you read this paper. You can download the 802.11 Attacks whitepaper directly from Foundstone.
