Well I just took a five second glance at a mirror site and worked it out
/debian/pool/main/ contains packages;
/debian/dists/sarge/main/binary-<arch>/Packages contains the list of
packages include md5sums;
/debian/dists/sarge/Release contains the md5sums of all of the
/debian/dists/sarge/Release.gpg contains a detached signature for
