Let's start with the basics. Do you have wpasupplicant installed? The
lines regarding WPA in your /etc/network/interfaces look okay but will
only function when wpasuplicant is there. You can also use a plaintext
string for the wpa-psk option if you wish. It makes configuring a bit
easier to understand (to humans) but could be a security risk. Also,
check to see that wireless-tools is installed as well.

From the output you have provided the card appears to based on a
chipset from Ralink. AFAIK the Linux drivers for these chipsets work
fine with WPA and I have had no issues connecting to encrypted networks
with such cards. I have a Ralink RT2500 based CardBus card myself that I
use as a spare.

The chances of getting it working from what I see is very good, it seems
to be mainly a software problem you are having :-)
Hope that helps and good luck getting it going.
