Honestly, RTFM of growisofs helps reducing your confusion. It runs
mkisofs itself and catches the output. So it is not neccessary to make
an iso image, you specify the same things you would do with mkisofs, eg.
a directory, multiple directories, or "graft-pointed" catalogue.
For big directories, the dirsplit utility can be used (from
www.freshmeat.net, the one in Sarge is not uptodate).

Unless you are going to use the UDF filesystem (writting on-the-fly)
formatting should not be necessary.

Looks like a usual 4.3GiB medium.
