Fitting a Round Peg into a Square Hole

I received an iPod nano for Christmas. It's just what I wanted but I was not looking forward to moving the 400+ albums I had in Windows Media Player - complete with album art - into iTunes. My anxiety was warranted: the result was a disaster. So, I took the opportunity to completely re-rip my entire CD library into iTunes. I chose to keep working with the mp3 format but bumped up the resolution from 128 kbps to 192 kbps. I must say that iTunes seems to do a slightly better job of finding album art than WMP, though I still found many albums for which I had to manually paste an image (either found on the web or scanned from the original).
