Don't you want to simply upgrade? The process is explained here:

Also read the release notes:

If you really want to reinstall, there are two ways:

1. Absolutely total reinstall
      * Back up your data, at least /home, possibly /etc, maybe also
        other locations
      * Download and burn the 8.04 CD (Desktop or Alternate version,
        depending on what you want)
      * Boot from CD and start install
      * In the partitioning stage, choose to format the disks. This will
        remove all your data as well as the old Ubunu version
      * Finish installation
      * Copy /home to the new system and check that the permissions are
        still ok (the user IDs must be the same between old and new
        system; no problem if you had only one user). You may want to
        NOT copy all of /home (which would copy the old configuration,
        too), but just selected parts from /home/<username>

2. Not so complete reinstall
      * Back up your data, at least /home, possibly /etc, maybe also
        other locations 
      * Download and burn the 8.04 CD (Desktop or Alternate version,
        depending on what you want) 
      * Boot from CD and start install 
      * In the partitioning stage, choose "manual partitioning", but
        choose NOT to format the disks. This will remove most of the old
        system, but will leave /home and a few other locations
        intact.DISCLAIMER: I have never done that, just read that it
        works (but the source was reliable). Back up
      * Finish installation
