Where to get good training on Ubuntu server 9.10

I currently just set up my Ubuntu server I am a noob to linux and I just started going to school for IT degree in Networking and security. I wanted to set up a shoutcast radio station and possibly my own email server but my lack of skills with linux is causing alot of troubles and I cant google everything. So i was wondering where I could get some decent training or just some good resources for learning about ubuntu server 9.10. Also my server is setup through VirtualBox and is installed right and working
