You might want to check out the Hymnals. There are both chant and song settings for the Morning, Evening, and Eucharistic offices. Looking in the 1982 Hymnal I didn't find the Athanasian Creed, but I did find the Nicene Creed in about 3 settings. This is all in the front of the Hymnal; the numbers begin with "S". I have a 1940 Hymnal at Church that I'll look in (it was my mother's from when she sang in the Choir) on Sunday; I'm quite sure there are service settings in there as well (and even a 2-page guide to chanting that I copied out for our choirmaster to give to the choir).

They are in the 1940 hymnal, all at the back.

A number of the hymns are metrical versions of the psalms and canticles. For example, "Tell Out My Soul" is the Magnificat for Evening Prayer. http://www.oremus.org/hymnal/t/t036.html
