A *very* strong recommendation: find a copy of Frisch's Essential Systems Administration, published by O'Reilly. Some of it's out of date, some more Unix than Linux... but read chapter 2, "The Unix Way". A *lot* will be a lot clearer.

I second and third that recommendation. A great exercise is to use that book as a foundation, and to realize that the “what to do” has not changed that much, but the “how to do it” changes hourly. Each year as I cull my tech library, the O’Reilly books are almost never passed on to the local library. I can count on them to show the best practices / philosophies / approaches, and then I research what has changed since it was published by directed web site searching and man paging.
