With this line you have in fstab :/dev/fd0 /floppy vfat defaults,user,noauto,showexec,umask=022 0 0
I would change user to users and check if /floppy exists. Then it's just a matter of "mount /floppy"
OTOH, why not try debian itself. Better than knoppix on a hd anyway

For cdrecording I usually use a script:
~$ ls -l $(which burn)
-rwxr-x--- 1 root cdrom 111 May 3 2005 /usr/local/bin/burn
~$ cat /usr/local/bin/burn
#!/bin/sh
cdrecord dev=/dev/hdc driveropts=burnfree,noforcespeed fs=14M speed=12 -dao -eject -overburn -v "$1"
When I burn an iso I just type "burn /path/to/file.iso".
