I agree with probono. OO is impossible to use unless you hdinstall on a PIV! So, if you're going to drop an office suite, kill off the bigger one, KOffice or OO. I'm not sure, but I imagine its OO.

Further, I agree with keeping the CDROM format. CD drives are much more readily available for demoing Linux to noobies.

Also, games are a big hook to get noobies into Linux. So keep some games. In fact, get rid of some in preference for more LAN party style games (bzflag, freecraft, etc).

If you can make room, add nvidia drivers! Its a big hassle to run scripts everytime I do a hdinstall to get my nvidia cards working right....

Oh, and keep teTex and QLyx which are very useful!

EDIT: Oh, keep Mozilla, I love Composer!
Also, why keep 2 kernels??? Support 2.6 in KNOPPIX 3.4 and maintain KNOPPIX 3.3 with kernel 2.4 for a short transition period!

Well, that's my 2 cents.
