No, it's the publisher who will get permission from ICEL, once they have accepted your setting.
One problem for publishers is going to be the fact that some of the new texts are not actually new at all — they are slight variations on texts which are already available free of charge. As such, ICEL will have difficulty in claiming copyright in those texts.

The Farrell settings are not official or prescribed, and it seems to me that you will be able to continue to use them, if you want to. (Personally, I find the line lengths of the music too long for comfortable breathing cumulatively; and Alstott has padded the text out to fit them.)
No one has yet addressed the fact that the 'official' texts of these two canticles are also Grail but have not been subject to the revision that the psalter has undergone. They and the other non-psalmic OT and NT canticles in the Divine Office (and Lectionary) are currently Grail versions from the "Grail Breviary Psalter". To substitute NRSV for these just because that's the scripture version we will be using goes against the previous policy, where these canticles were not tied in to JB or RSV or any other approved translation. In addition, we have the ICET versions of the Benedictus and Magnificat as official alternatives.
