I have a 40GB iPod.
I am using a pair of Sennheiser HD25. They sound incredible! You maybe able to find them new in the Web for around $180. http://www.americanmusical.com/item--i-SEN-HD25--brand-240--src-D0401IN0HAMS0000.html
I also use my iPod going direct to my Threshold amplifier in my bedroom. I am using a cable that we developed for it in our company (www.slivercircleaudio.com). I can send you a picture of it if you want. I was using a gold plated cable from RadioShack but there is no comparision with ours.
