Here is an example /etc/network/interfaces snippet which worked for me
about half a year ago (that was at a conference; I have not used WPA
since then):
------------------------------------------------------------------------
auto eth1
iface eth1 inet dhcp
wpa-ssid YOUR-ESSID
wpa-key-mgmt WPA-PSK
wpa-pairwise CCMP TKIP
wpa-group TKIP
wpa-psk SOME-LONG-SECRET-STRING
# to generate the wpa-psk string, run: wpa_passphrase YOUR-ESSID YOUR-PASSWORD
------------------------------------------------------------------------
As Andrew has pointed out, you need the wpasupplicant package and its
daemon has to be running. (IIRC, it is started automatically when you
bring up an interface that has wpa-* statements in the interfaces file.)
Based on your "iwlist" output I suspect that you might have to change
the wpa-pairwise line to this:
wpa-pairwise TKIP COMP
