English version of the music is available on the Melkite GMA web site (
http://www.melkites.org), at least a sample of a couple of the chants. You can buy the complete CD from there as well, I believe.
You can find the words to the songs of Fairuz' CD here:
http://www.6arabsongs.net/Lebanon/fairouz/good_friday/ . These are largely the hymns we chant on the evening of Great and Holy Thursday and Friday.
Apart from a transliterated version of Fairuz' songs, I doubt you'll find any transliterated texts around.
In our eparchy, all our texts are either in Greek (using the Greek alphabet), Arabic (in Arabic script), or in English.
