1. if you arrive really late, don't venerate the icons right at the front on the iconostasis.
Huh? why not?
“Arriving later causes a distraction for others who are praying.” http://www.antiochian.org/sites/default/files/ChurchEtiquetteBooklet.pdf
“Some rules of thumb: – Those who arrive late should generally refrain from partaking of the Eucharist that day as ‘proper preparation’ for Holy Communion assumes the effort of arriving on time service. One should refrain from venerating icons in the front of the church, etc. for the same reasons given under ‘Lighting Candles.’” http://russianreport.wordpress.com/religion-in-russia/orthodox-worship-understanding-etiquette/
“Try not to interrupt the Liturgy with your entrance”http://stpaulsorthodox.org/church-etiquette/members-catechumens/
“we each have a duty as serious worshipers to see that a respectful decorum and atmosphere are maintained so that the congregation can pray sincerely, peacefully without distractions, and meaningfully” http://stgeorge.mi.goarch.org/about-us/church-etiquette
“The time to arrive at Church is before the Divine Liturgy starts. If you should arrive after the service begins, follow the guidelines under “Entering the Church” below so your entrance does not interrupt the service. The best way to avoid entering the Church at an inappropriate time is to arrive on time.” http://www.stgeorge.nh.goarch.org/orthodox-resources/church-etiquette/
"We strive to arrive by the time the priest says, “Blessed is the Kingdom…” at the Divine Liturgy, or “Blessed is our God,” at most other services. This is the beginning of the “corporate” prayers of the whole Body of Christ. Thus, it is proper to arrive before the service starts. If forced by external circumstance to arrive late, one must enter quietly, minimizing distraction, and preserving the spirit of worship. It has become common practice to refrain from communion if one arrives after the Gospel reading. If one arrives during the Epistle or Gospel readings, the homily, or the Great Entrance remain at the back of the church until complete. Arriving in a timely fashion avoids distracting one’s brothers and sisters in Christ, and prevents inadvertently drawing our attention away from our worship of our Good God." http://stcyril.us/church-etiquette/
