Switch from bz2 to gzip and you may get home before Monday morning!
bzip2 is terribly slow for large byte streams - I once found it faster
move data uncompressed than to use bz2 (gzip was faster yet).  bzip2
is great if you have to download a disk image over a 110 Baud modem.

Sorry, I don't know about parallelizing tar.
