Yes, there is. Believe me on this one, it is called the Orthodox Standard Prayer Book. My mom is Eastern Orthodox and she has a prayer book by that name. You can get it from any religious store or an Orthodox church.
Yes. At every orthodox church. Also the Eastern Orthodox believes itself to be the only non-heretic church, the only God-made denomination because it preserved unchanged all the original teachings of the First Seven Holy Councils
