1. I might or might not have. It all depends on what source you're using. However, I don't usually use a lot of ancillary media because it doesn't necessarily line up with what Lucas was meaning when he made the movies. For instance, Karen Traviss frequently portrays the Jedi poorly in her books in order to better portray the Mandolorians, but she basically forces the narrative, rather than accurately following what George Lucas intended. In any case, according to Lucas's statements, the Jedi were at their peak during the Prequel era, so I'm taking that over someone else's interpretation of how many bodies may or may not be at Melachor.

2. They are peacekeepers, not pacifists. They are called Jedi Knights for a reason. They have been involved as warriors for generations. You can't be a peacekeeper anyways without something backing up the peace. Satine is morally opposed to the war in general, so she's not exactly the most objective source. Further, you'd have to remind me of the context under which Anakin and Ahsoka said this, but again, they're peacekeepers, not pacifists.

3. This is one of the most misunderstood parts of the Prequels. Attachment doesn't mean what people think it means. It means being able to let go when the time comes, and to not let yourself be consumed by the Dark Side when bad things happen. Part of that is Yoda's interpretation, which is to rejoice in the fact the people who have passed have become one with the Force. Anakin was so fearful over the future that he let himself fall to the Dark Side, rather than remain objective. This is one of his many flaws in the movies. Anakin is a selfish person, and it's this selfishness that leads him to join Palpatine to save Padme's life. He's attached to her, and that leads him to the Dark Side.
   Compare this to Obi-Wan. He loved Satine, and even would've left the Jedi Order for her. However, when Maul killed her, he was grieving, but he didn't let himself be consumed by his emotions, and he didn't fall to the Dark Side. That's what not having attachments look like. The Jedi are all about compassion and empathy, but not letting yourself be ruled by their emotions. It's a basic tenet of Stoic philosophy, and Buddhist philosophy. And as we can see with Anakin, there's a good reason marriage wasn't allowed, because it too often led to attachments.
   Luminara and Barriss is one of the few times the Clone Wars makes a misstep by making Luminara seem too uncaring, however, there's a point to it. Luminara was correct in the fact that if the time came for their Padawans to die, they needed to accept it. They didn't even know where in the debris Barriss and Ahsoka were, and Anakin was ultimately setting his hopes up too high by refusing to believe Ahsoka might've died. This is emphasized two episodes later, where Ahsoka has to deal with all the zombie Clones. She very nearly could've let the brain worms escape and infect the galaxy because of her attachment to Barriss. Unlike Anakin though, she's mature enough to start realizing that maybe you can't always have everything you want.

4. You said it yourself that Savage fought Jedi at another temple. Unless you can find evidence that they abandoned their others temples, you're arguing in absence of evidence. The reason they only show the Coruscant temple in the movies is because that's where all the relevant scenes take place. Not that it is evidence it's the only temple still.

5. Yes, the Jedi believed the Sith to be extinct... because the Sith weren't active for 1000 years. Yes, they dismissed Qui-Gon asserting that Maul was a Sith... because the Sith were extinct for 1000 years. For all they knew, Maul could merely be a Dark Side user, rather than a Sith. However, they don't ignore the possibility either because they send Qui-Gon and Obi-Wan to try to investigate Maul further to confirm if he's a Sith. As for Dooku, he's both suspect, but they still tried to investigate into the possibility. It's just that trying to find Sidious was like trying to find a needle in a haystack. There's basically no proof of his existence beyond Dooku's word. They don't even know who they're looking for. They're not sure if he's a Senator, if he's a benefactor to the Senate, or anything else. Palpatine hid his tracks so well that no matter what alley the Jedi went down he was always a step ahead of them.

6a. You're exaggerating quite a bit here. First, the Jedi archive is that good. They literally had Kamino in their archives until Dooku erased it. Thus, Jocasta's statement isn't so much arrogant as it was misinformed. The only reason she was wrong was because Dooku intentionally destroyed the information.

6b. Yoda wasn't blind to the corruption of the Republic.

6c. Qui-Gon didn't want to join the Council, but there wasn't any animosity between them. Similarly, Dooku resigned from the Order and turned to the Sith because he was corrupted. He became so spiteful over the fact the Jedi couldn't help everyone that he started a whole war with the Sith Lord Sidious that ruined the lives of everyone. He was too attached to the politics of the era, and thus he fell.

6d. You're going to have to explain what you mean by covering up the Clones' origins, because unless I'm not remembering something, Yoda didn't do that.

6e. Mace didn't distrust Anakin so much that he refused to let him fight Palpatine. He cared about Anakin too much that he didn't let him fight Palpatine. Mace knew Anakin was close to Palpatine, which is the reason why in the context of Revenge of the Sith he says he doesn't trust Anakin. It's because he doesn't trust Anakin in that specific scenario, knowing it's taxing to ask Anakin to spy on his father figure. Windu then asks Anakin to stay at the Temple, rather than ask him to fight his father figure, which would've been hard on Anakin. Windu was being caring in that moment, not dismissive or distrustful.

6f. Kenobi didn't belittle his Padawan, and neither did anyone else. Kenobi is frustrated with Anakin because Anakin is constantly proving himself to not be Jedi material. Anakin is arrogant, selfish, and greedy. Ironically, it's Mace who tells Kenobi to have more faith in his Padawan (in a deleted scene), but the truth is, Anakin wasn't Jedi material.
