Some that I like: Respect the Process (about commercial filmmaking), some old podcasts from the 2007-2009 tribeca film festivals (search "meet the filmmaker," maybe), The Moment with Brian Koppelman (esp. the ones he did with filmmakers when it was still on grantland), austin film festival's on story podcast.
Also WTF, Fresh Air, Here's the Thing with Alec Baldwin, and The Nerdist (the last 4 are listed in descending order of my preference, and are all not film-specific but feature lots of episodes with directors/actors/etc.)
I know this doesn't help you much now, but in the future why bother updating immediately? The updates always seem to be riddled with bugs, but if you give it a couple weeks a patch usually comes out that improves things dramatically.
Why do you want a camcorder? I think the general consensus, these days, is that you get a better picture quality for your $ with a DSLR or mirrorless interchangeable lens camera than from anything you're going to buy for $1500 all-in-one.
Unless you're doing events or news or something, I would invest the money in a lens, or lights, or what have you.
I would think about a high-quality, fairly wide-angle prime (wide angles don't have some of the issues a longer lens would have, so you may well be OK without IS). Lenses are fairly cheap to rent for specific projects, but one great 35mm can also shoot an entire project by itself. And if you have access to the 70-200, that's a great complement.
I don't have much experience editing in Resolve, though I agree that it's the best color correction option out there. I too wish there were a better workflow between PP & DR.
I often find myself using Colorista III in order to stay within the Adobe workflow, which isn't a horrible solution, but it's less than ideal.
I used an H4N/ME66/K6 combo for a long time. It's not the worst solution, but I enjoyed the Tascam DR60-D at that price point more.
I thing I would generally have the recording level of the Zoom set to ~55, with the mic ideally ~8-18" from the talent's mouth. It's a pretty hot mic, but quality definitely decreases as you add more gain. I wouldn't do any limiting/compressing in the recorder, just a clean 24 bit wav file.
