Catholics (there is no such thing as "Roman Catholic", that is a popular misnomer) use the complete Bible which includes the Old Testament that Jesus Christ used, the Septuagint. The Septuagint does contain the books of 1st and 2nd Maccabees but it is most certainly not called the "Maccabees Bible", just the Holy Bible or Sacred Scripture. The Orthodox Bible contains all kinds of books which were not in the Septuagint, do no, we do not use the same Bibles.
The book of Maccabees is considered deuterocanonical, meaning it is accepted by some Christian denominations but not all. It is included in the Old Testament by the Catholic and Eastern Orthodox Churches, but not by Protestant denominations.
For Roman Catholics and Eastern Orthodox, it is in Daniel chapter 13.
Roman Catholics believe in Papal Primacy, Papal Infallibility, the Immaculate Conception, and Purgatory while Eastern Orthodox people do not. Roman Catholics believe that the Holy Spirit proceeds from the Father and the Son, while Eastern Orthodox people believe that the Holy Spirit only proceeds from the Father.
The Eastern Orthodox Church uses the Bible. The books in their Canon are slightly different than that of the Roman Catholic, but they also use 3 Maccabees, Psalm 151, and 1 Esdras.

That's a long an complicated question. The short answer is the Roman Catholic Church celebrates most holidays on the Western Calendar while the Eastern Orthodox use a slightly different calendar known as the Eastern Calendar. Some years the dates are the same and others they are different. The Roman Catholic Church structure is similar to the Eastern Orthodox. However, the Eastern Orthodox setup a church in each country (generally, America being one notable exception) whereas the Roman Catholics have a world wide structure.
The catholic church is sometimes considered the collection of churches that developed out of the Great Schism (namely, the Roman Catholic Church and the Eastern Orthodox Church). Although I have never heard someone use the term "catholic orthodox church," I would consider it to be referring to the Eastern Orthodox Christian religion.
