There is no link as in, "the Cortana letters were originally intended to have a major effect on the Halo storyline, and thus have some deep and hidden meaning to them," no, but as in "Bungie has used ideas from previews games in Halo, so these letters could have a link to the events of Halo 3, or the time between them while Cortana was at High Charity."
