You can boot off a rescue floppy (like tom's root and boot disk http://www.toms.net/rb/) or a live CD (like knoppix http://www.knoppix.org/), mount your root partition and edit /etc/passwd. Look for the entry for root, remove the "x" from that line,

eg:
root:x:0:0::/root:/bin/bash

becomes
root::0:0::/root:/bin/bash

Now save the file, reboot and now root will not have a password. Don't forget to assign a password for root straight away with the passwd command.

Certainly. If you're installing an OS, just pop in the install CD and overwrite the whole drive with the new install.

Or pop in a knoppix CD and use "shred" to secure delete the entire hard drive. This basically low level writes over the whole drive several times to make sure no data can ever be recovered.

Or if it has a floppy, there's some floppy tools that will do the same. google for "secure delete floppy" or something like that. Here's one http://dban.sourceforge.net/
