Are you quoting somebody there, or is this your own list. I'll try to address the points raised:

 1) "Hearsay" is rumour received from others that one did not personally hear oneself. That does not describe Table Talk, which is essentially a primary, contemporary source of edited notes taken down by scribes. Mein Kampf I believe was also began as a text dictated by Hitler, rather than written by Hitler - is that hearsay too? And what of notes taken by Speer - is that "hearsay"? (Interesting you note that Bormann was anti-Catholic. Why then would a "devout Catholic" as you term Hitler, appoint an "anti-Catholic" as his Private Secretary and the defacto Deputy Fuehrer?)

2) Multiple translations - a valid issue to raise, but given that Hitler and his henchman all, strangely enough, conversed in German, we are dependent on translations in all cases - whether it be Mein Kampf, Inside the Third Reich, or Table Talk. The fact that authors like Kershaw, Bullock, Encyclopedia Brittanica and Toland all quote from Table Talk is evidence of its essential bone fides - though if you are aware of alternative translations provided by reliable sources, please do present them (or bracket them as "also translated as").

3) The "bias" of the translators. Can you provide reliable sources for this please.

4) I do not know what you mean by "the Table Talk thoughts do not occur in other private or public conversations". Table Talk contains all sorts of quotes which are reinforced by other sources! To pluck one from the countless options: Speer (whom you view as a reliable source) says that Hitler made "harsh pronouncements against the churches to his political associates in Berlin" and specifically notes that Bormann relished to take down Hitler's harshest comments on the Churches. Goebbels diary (per Kershaw & others) is another source, confirming Hitler's thinking on the Church Struggle. 

5) You say "Nowhere does Hitler denounce Jesus or his own brand of Christianity". This comment seems to suggest that you are indeed willing to accept the validity of at least some of the Table Talk text. Good. So please note: the text says Hitler believed "it is certain that Jesus was not a Jew" and that the Apostle Paul "falsified" Jesus' doctrine. These alone are the words of a heretic, not a "devout Catholic". Agreed? As a sign of good faith, it would help at this point if you renounced the claim that Hitler was a "devout Catholic". Beyond this, the transcripts are thoroughly peppered with denunciations of Christianity.

 6) The anti-Christian pronouncements contained in Table Talk are entirely consistent with the Nazi efforts to promote positive Christianity as a substitute for Christianity. The renunciation of the Bible and Jewish origins of Jesus (which "positive Christianity" entailed) was to give him a "false birth certificate" as Cardinal Michael Faulhaber put it in 1933, and the notion of the myth of blood and soil was, as Pope Pius XI wrote in Mit brennender Sorge in 1937, entirely inconsistent with Catholicism and Christianity more broadly: "The peak of the revelation as reached in the Gospel of Christ is final and permanent. It knows no retouches by human hand; it admits no substitutes or arbitrary alternatives such as certain leaders pretend to draw from the so-called myth of race and blood". Hitler, plainly was not in "good standing with the Church of Rome" in 1937!
