i cannot address all that is being said here. I am not with the JWs. I am a Bible Student as was Charles Taze Russell. There are indeed many, many false accusations and distortions of history being told about Russell, what he taught, what he did, etc.
I will be making references to my CTR site:

I have been studying Russell's works and life for more than 55 years. I do not claim to know absolutely everything about him, and I still come across things that I did not know before. I do try to be as accurate as I can.
Russell was never a member of the Jehovah's Witnesses organization; he did not believe in such authoritarian sectarianism. Nor did believe in the organization method of salvation that Rutherford created and which is evidently still taught today by the JWs.
It would not be fully accurate to say that more than 75% of Bible Students "left the organization." They did leave or were separated from the legal entity the Watch Tower Bible and Tract Society, which could be referred to as legal business organization, but as the term "the organization" is often used by Jehovah's Witnesses, that would be misleading. The more accurate statement would be that the majority of the Bible Students worldwide rejected Rutherford's "Jehovah's visible organization" dogma; in effect, they refused to join themselves to "the organization". I will say that I don't know that Russell ever used to the word "organization" regarding the Watch Tower of his day. As a legal entity, I suppose the Watch Tower Bible and Tract Society of that time could have been referred to as an organization, but it was definitely not an "organization" in the sense that Rutherford and the JWs later made it to be.

I had some correspondence with some one workng on the book, "Nelson Barbour: The Millenium's Forgotten Prophet", before the book was published. If I remember correctly, I was sent a preliminary copy. At any rate, the thing I remember objecting to mostly was the reference to Barbour as a prophet. I have not seen Shultz' "A Separate Identity". I have ordered a copy of the book.
Russell was definitely never a member of the Freemasons.

While not all that Russell was expecting for 1914 came about as quickly as he thought, as far as Russell is concerned, 1914 was not a failure. Russell was never expecting Christ to return in 1914, and he did not spiritualize 1914 due to any failure of such an event. About 1872, Russell came to realize that Christ's return would not be in the flesh, but in the spirit. In 1876, he accepted Barbour's conclusion that Christ had returned in 1874.
Russell was expecting that the earthly phase of the kingdom would be established in Jerusalem in 1914 or shortly after; he did not change this expectation to something spiritual; I would say that most Bible Students are still expecting that the kingdom will be established in Jerusalem, whenever that may be.
One speaks of dates for "the end" as being 1874, 1914, 1975. The two dates that would be related to Russell would be 1874 and 1914. I am not sure what is meant by "the end", but usually this is supposed to mean "the end of the world."
Of course, Russell, before 1874, had no expectations regarding 1874 at all. Many Second Adventists were expecting the earth to be literally burned up with most its inhabitants eternally lost while a few would be saved. Russell rejected that idea. It was not until 1876, two years after 1874, that Russell accepted Barbour's conclusion that Christ had returned in 1874.

As far as 1914 is concerned, before 1904 Russell accepted Barbour's conclusion that the time of trouble had begun in 1874 and that it would last for 40 years, thus ending in 1914. Before 1904, then, Russell was expecting that the world would be at peace in 1914. Russell never held to any views similar to what the JWs claim about Armageddon. He viewed Armageddon as a period of time when the people of the nations were to be chastised (not eternally destroyed). Such chastisement was to prepare them for the kingdom blessings to follow.
In 1904, however, Russell changed his view concerning the time of trouble, rejecting the view that the time of trouble had begun 1874. He then believed that it was to begin, not end, in 1914, and that rather than peace coming in 1914, the nations would be in the time of trouble. He was definitely not expecting "the end of the world" in 1914. He was expecting the Gentile Times to end in 1914, and the time of trouble was to begin in 1914.
Regarding the time of trouble, one may find more in the the posting, "Beginning of the Time of Trouble - Quotes From Russell" on my CTR site.
Russell presented several different scriptural methods for arriving at the date 1914, all of which the JWs have dropped except one, that of Daniel 4.
Russell accepted 607/606 as the date of Jerusalem's destruction because of the chronology based on the Bible, and the many ways this date interlocked and produced a symmetry for many other time features. Still, he was not dogmatic about this, and not all Bible Students in his day accepted his view that Jerusalem was destroyed in that year. Russell mentioned this several times, but he never insisted that one had to accept the 606 date or in any other of the chronology in order to be accepted in fellowhsip. I have a collection of research on one of my websites related to Russell and 1914, and also another regarding Russell, authority and organization.

Russell did nothing wrong regarding Miracle Wheat, despite all of the Eagle's distortions. I have much information related to this; one may click on "Miracle Wheat" option on my CTR site.
Contrary to much false information often being spread, I do not believe that Russell did anything wrong towards Rose Ball. I consider this matter incomplete, as evidently no one sought to verify any of the accusations made in court with Sister Henninges, who had married and was living in Australia with her husband at the time of the divorce trial. Sister Henninges, however, was of the belief that Brother Russell had "gone out of the truth" because of his beliefs regarding the new covenant, and thus there was some friction between her and Russell over this. As far as I know Sister Henninges during her lifetime never mentioned, affirmed, or disaffirmed any of the statements attributed to her or regarding her that were presented in court. At any rate, many do like use the hearsay testimony presented in court as a weapon for character assassination of Russell. Due to the the fact this was considered too old to be accepted as testimony in court, the testimony concerning Miss Ball was stricken from the records. Nevertheless, in all that testimony that Mrs. Russell presented, it fell short of accusing Brother Russell of adultery, and Mrs. Russell herself stated that she was not accusing her husband of adultery.
