Also, does the Russian Catholic Church liturgically venerate the Russian saints glorified by the Russian Orthodox Church i.e. New Martyrs and others?
Alex, the answer is yes. I led a Moleben to Hieromartyr Pavel Florensky this year on his Old Style feast day (armed with a new icon of St. Pavel from our Dave/Chtec). We did the same for St. Seraphim of Sarov and sang his Akathist.
Pavel - the Russicum doesn't have a calendar per se. Orthodox saints are commemorated, and those Greek Catholic martyrs such as the Pratulin Martyrs, Hiermartyr Leonid, etc. are added as appropriate. And yes, Fr. Lawrence in Melbourne keeps the commemoration of many Orthodox saints.
