Sorry if this has already been covered, I walked into the middle of the
thread.  But I get by just fine using:

tar -cv  -L 1000000 -F myscript -f archive.tar stuff/to/backup

This creates chunks that are 1 GB in size.  myscript is actually the backup
script that calls this tar command in the first place.  When called in this
instance it provides the next archive name.  That way I end up with
backup00.tar, backup01.tar, etc.  When all done I gzip the lot of them.  I
picked 1 GB because after gzip it is safely small enough for a cdrom.

I don't think you'd want to split tar.gz files because you'd need to put them
back together to restore anything.
