Some good Ricky / Karl stuff here: http://www.youtube.com/watch?v=NQBlZIXu3Yg
Karl Pilkington and Ricky Gervais Podcasts Page 2
Worth listening to if only for Monkey News.
Try and get hold of the shows where they sat-in for Jonathan Ross on Radio 2. Some of their finest.
Look up this channel on YouTube: www.youtube.com/andyns
This chap has uploaded an enormous amount of Gervais/Merchant/Pilkington XFM st stuff. Much of the material is repeated on the podcasts. Don't have to pay for this; find the stuff you like most, or get a taste for their work.
There's more on pilkipedia website. 
I've been downloading some of the new Ricky/Stephen/Karl podcasts.
I also found a good site to catch up on the Archives if anyones interested.
