the book UNIX Bible comes with Slackware CD1 and a second with some other stuff.
CD1 is the one needed for install. the second is just kdei and gnome iirc. that is, internationalization files for Kde an the Gnome desktop.
i prefer Icewm but...
there are minor diferences between Debian and Slackware, not insurmountable (Knoppix is a customized Debian).
EDIT hmm, might be an older Slackware version though, my book is not exactly new so... /EDIT
