Just purchased and working through O'Reilly's 'Running Linux', covers a huge amount cencerning configuration, setup and troubleshooting most aspects of linux installations like SuSE & Red Hat.
A good place to start IMHO.
Not to mention these forums incase things go pear-shaped (which they most likely will, at some point). Forums over at www.justlinux.com
are also excellent.
The linux newbie guide at http://linux-newbie.sunsite.dk/
is also worth a look.
