Regarding point 5, I would also recommend https://www.researchrabbit.ai/. Last I checked, I found it more useful than ConnectedPapers, and about as useful as Elicit (with each of those tools having different strengths). I find ResearchRabbit to be especially effective at discovering relevant literature, even when starting out with very few or just one single paper(s).
Thank you!
