For pure reference, I've always liked my "Linux in a Nutshell" book (O'Reilly publisher), which has a huge section with all of the commands and options. It even has sections on "vi" and "emacs". Google and man pages take care of the rest. (Also, since CentOS is so similar to RHEL, anything taught in a RHEL book tends to carry over.)
