Excellent summary, TheListener!
To add a bit to what you said about 2 Chronicles 36:20, the passage unambiguously states that the Jews would be servants to Nebuchadnezzar and his dynasty -- not to kings from the Persian dynasty of Cyrus. Indeed, it explicitly states that this servitude would be until the royalty of Persia began to reign. This eliminates any possibility that the Jews were in servitude to Nebuchadnezzar's dynasty after 539 B.C. Putting this together with the unambiguous statements of Jeremiah 25:11, 12 and Daniel 5, it's a killer for Watchtower claims.

: CT Russell did his early calculations of 1914 based ENTIRELY on mathematical calculations derived from imperial measurements of interior wall spaces of the Pyramid of Gizeh.
Not true. M.J.'s comments are correct.
The 1914 chronology was first published by Nelson Barbour just after mid-1875. Russell learned about Barbour's calculations in early 1876, got together with Barbour, and published his own version of the "Gentile times chronology" in the October 1876 issue of The Bible Examiner. In 1877 the two of them published Three Worlds, in which this nonsense was set forth in more detail. It was not until 1880 that Russell mentioned the Great Pyramid at all, in the September, 1880 issue of Zion's Watch Tower (p. 135, Reprints). Here he said the the Pyramid's topstone represented Christ, and the rest of the Pyrimad represented Christ's body of anointed followers. This was apparently due to Russell's reading Joseph Seiss' book Miracle in Stone which was published in 1877. Russell's next mention of the Great Pyramid was in the May, 1881 issue of Zion's Watch Tower (pp. 224-5, Reprints). Here he claimed that various measurements taken in the "grand gallery" represented the years 1874, 1878 and 1881 -- no mention of 1914 -- which were prominent in his prophetic scheme at that time. So far as I can see from the Reprints Index, there are no further mentions of dates in connection with the Pyramid until after Russell published Thy Kingdom Come in 1891.
In view of the above facts, Russell did not base his 1914 chronology on the Great Pyramid, but used it for 'corroboration'.
