Zerubbabel

Here in the Scottish Rite Northern Masonic Jurisdiction the primary character in the 15th (Knight of the East) and 16th (Prince of Jerusalem) degrees is Zerubbabel. The role is an exciting one to play as he stands up bravely to kings and nobles alike in the pursuit of his principles. Despite being a prince of the house of David he never, in these moral plays, takes the road of reconciliation , but always steers by his principles regardless of the consequences to him or his people. He is a complicated semi-heroic character and one I can relate to on a personal level (just ask the poor Deputy for Maine).

As always there is a thirst for more knowledge when studying a degree, so the question is where to learn more about Zerubbabel. Thus far I have read Ezra, Haggai, Zechariah, and Sefer Zerubbabel (or the Apocalypse of Zerubbabel). Are there other good texts out there for the story of Zerubabbel?

(update: No soon is this posted than I found Esdras from the Apocrypha and our hero spelled "Zorobabel".)
