Any old Network card should work. The empeg doesn't do 100baseT, so your stuck with 10. If you want to plug your empeg straight into your computer, you'll need a crossover ethernet cable. Once you plug it all up, you'll need to set an IP on the empeg through emplode's network settings with the USB or Serial cable, sync, then you'll be able to connect with ethernet. If you have a hub laying around, you can just use that and straight plain ol' ethernet cables. Any questions? =]
