For gz use the -x option,  bzip2 use the -j option, or after creating
the tar file use gzip or bzip2 to do the compression.

My version of tar does not allow compressed archives as multivolume, and
it also prompts for an enter after each volume is created. Thus it is
not totally hands free.

Unless someone else can tell you different it appears that you would
need to move the archive to a new name before you press enter, and then
compress the archive after creating it.

Or you can create one big archive and then split it into smaller pieces
for storage.

If this is being used for backups you might want to look at
mondoarchive.  It easily makes multiple compressed images ready for
burning to cd of whatever size you specify.
