Linux Admininstration Resources?

shadfc asks: "I'm starting a new job as the system administrator for a small company in Tampa. They currently have 10 Red Hat servers (they are open to distribution change) that have not been actively maintained for a few months. I'm a Junior in College with a decent amount of Linux experience, but this will be my first job in this kind of position and responsibility. I'm asking for resources that can help fill in the holes in my knowledge and help make me a better administrator. Quality books on the subject would be preferred, but any advice is welcome. Thanks!"
