Did you set the ESSID with iwconfig? The output of "iwlist wlan0 scan"
in your first message showed that your access point hides its ESSID. I
think this means that it will only accept connections from clients which
know the secret ESSID before they connect.

Also, check the output of "iwconfig wlan0": Is the ESSID set correctly,
does it display the MAC address of the right access point?

If the above is all OK then it might be a problem with dhclient. There
are two DHCP client packages in Debian, "dhcp-client" and
"dhcp3-client". Make sure to try it with both of them.
