Thanks ! 

To actually get the Radiant set up, you may need this.

Instructions are there. To make a map inside Radiant, it's normally the same as WaW since they use the same thing.

For zombie models, you have to do them yourself, but I do have some MOTD zombies that work and sadly, the updated version (1.1) is in CFGFactory. I'd love to upload them here, but I'm too lazy.
