[Wlug] In Search for Unix / Linux Career

Folks, I need some help here. I am a Linux / Unix newbie and I am wondering how I can painlessly (although I realize that i must put in a lot of hard work) get a carrer in the Unix / Linux world. I am a CCNA, MCSE, CCSA, N+ and A+ and I am comfortable in the networking field. I am comfortable with the Cisco IOS, Checkpoint as well as the microsoft shit. But after realizing that Microsoft is not my very friendly area, I am leaning towards going into the Linux / Unix world. Where should I start? I dont want to spend time going to school and I am confortable with self study. What certifications would you recommend and what books do I need? Thanks, John
