you need either printable CD's and a printer capable of printing on CD's, or a sheet of sticky CD labels you can print onto and then stick the on the CD's.
the labels are like this
http://www.amazon.co.uk/CD-DVD-Matte-Labels-10 0pk/dp/B00009EJ4P/ref=sr_1_2?ie=UTF8&s=electro nics&qid=1250088067&sr=8-2
then you will need software to print the labels, some burning software has this already (like nero) and I would also suggest a tool to ensure you stick the labels onto the discs centrally
this is the full kit
