Upgrading iTunes

I have iTunes version 7.1.1. I understand that they are up to 7.3.2. I am interested in upgrading because I want to be able to download the DRM-free versions of song, but I've heard that people can have troubles with synching their iPods with the later version, so I am hesitant to do so. Comments, anyone? Is there anything I should do before I upgrade?

How I know I've really got it bad

I spent some time hunting all around the office for a yardstick so that I could go down to the office gym and practice my bo (stick fighting) form.

I couldn't find one.

It's rather amusing how frustrating I found this to be.
