I totally splurged and bought a copy of A Guide to Greek Traditions and Customs in America
(second edition) by Maria Rouvelas. Fab book, explained a lot to me, and this edition has added (lemme look here) a section on "The Global Community...greek americans in the wider text of the Orthodox faith and the Greek Diaspora" So far a very interesting read, i recommend it. website here:http://www.greektraditions.org/
althouhg i actually got it from http://www.greekshops.com/
because it was faster. Ran with shipping about $42. told you I splurged! Prolly because it only comes in hardback.
