One that I usually assign to my catechumen class members is Christ in His Saints by Patrick Henry Reardon.
It is a good historical accounting using the lives of almost one hundred and fifty saints and heroes from the Scriptures - everyone from Abigail to Zephaniah, Adam to St. John the Theologian. This well-researched work is a veritable cornucopia of Bible personalities: Old Testament Saints, New Testament Saints, "Repentant Saints," "Zealous Saints," "Saints under pressure". However it does not answer your questions about Western Orthodox Saints for that I suggest the following books:
a. The Saints of Anglo-Saxon England - Volume 1 (9th-11th centuries) by Vladimir Moss
The first is a series of lives of Orthodox martyrs and strugglers from England from the centuries just prior to the Norman Conquest, who are largely unknown to us. Describes 19 saints from 779 to 934.
b.The Saints of Anglo-Saxon England - Volume 2 (9th-11th Centuries)by Vladimir Moss
The second in a series of lives of Orthodox martyrs and strugglers from the land of England from the centuries just prior to the Norman Conquest. This volume contains the lives of seven 10th century saints, including St. Dustan and St. Edward.
Otherwise, you may need to get a Catholic Saints Volume and read only those Saints who were glorified prior to the Schism.
