Update after using the new build for a few days:
I left the settings alone for a stretch, and didn't experience any issues. So I eventually went back and altered the settings to like what I mentioned above, and all was well for a couple days, until recently when powering on/starting the player in the middle of a playlist of 5 files. This had all the characteristics of the pause/play issue, where the wps becomes unresponsive; the only difference is the files didn't pause this time, the wps just became unresponsive, so that's a step in the right direction. Still had to hard reset with a paper clip in order to use the device again, and it automatically resumed to the file where the wps got stuck, and had to reset again (3 times total).
I have a sneaking suspicion it may have something to do with setting Startup/Shutdown > Start Screen to Resume Playback, so I changed that to Recent Bookmarks and see if I get the issue again.
One other thing is that many of the files seem a little bit crackly, but that might just be the podcasts themselves. It's not something I've noticed before, either with this device or those podcasts, so it may just be a coincidence, but it's just something I noticed. (And it's just slightly crackly, it doesn't really get in the way of anything and can be missed if you're not looking/listening for it.)

Hi,
sorry for the late answer. The build I provided (https://www.dropbox.com/s/17mlziuobfvjunh/rockbox_nwze380_buttonfix.zip?dl=0) is supposed to fix the issue with buttons not working (due to temperature or other things). Can you confirm that it works or do you still have issues ? Apparently this build seems to have issue with USB mode (panic), I am not sure why, I'll upload a new build tonight or tomorrow, just use bootloader usb mode instead if you use this build.
Regarding the issue of using the power button to boot the device, I have some bad news. The short answer is that it is impossible.
The long answer is that the power button (contrary to all other buttons) sends a special signal to the soc. When the soc is powered off, this signal means "enter recovery mode". So if you press if from power off, the device will boot straight to recovery mode instead of our bootloader. If USB is not plugged then the recovery mode will timeout after 2 or 3 seconds and eventually boot rockbox. So you would need to hold the power button for 3 to 4 seconds to boot: that's a VERY long time. Now you might wonder how the OF does it. The answer is that the Of never powers off, it merely goes to deep sleep and thus avoids this problem.
Conclusion: unless we implement deep sleep (which is a lot of work for little benefit it seems), we can use any button to power off EXCEPT the power button...

Yep, that's the build I've been using this week, and I can confirm that I've not had any issues with the buttons not functioning if the device wasn't sufficiently warm. So that's that sorted, nice work!
I'll give the other build a try when it's available to see if it still panics in usb mode. That's not any sort of show-stopper; personally I only used it to recharge the battery when I was listening to something, and didn't really have use for the mouse feature when plugged in. The only other issue I've had was that lockup on the wps screen, but it was only once and at least it's not pausing every six seconds. I can report that since I changed the Startup/Shutdown > Start Screen away from Resume Playback (to Recent Bookmarks) I haven't experienced the issue, but it's only been a day so far.
As for the power button, not sure that's a real problem in the grand scheme of things. As long as it turns on and off, I'm not sure if it's much to be bothered about, as long as it doesn't require a paper clip and the reset button.
EDIT
I spoke too soon. Just had the problem again where the wps is stuck, buttons won't work... and it's pausing every few seconds again. Two files were in the playlist, and it was bookmarked to start about 5 minutes into the first file. Can't get it to do much of anything at the moment. Press a button, nothing happens, and the wps will change screens, like if I hit the back button, but only after about 20 seconds or so, and the screen veeeeerrrrryyy slooooooowwwwwllllyyy fades in. Volume, play/pause, etc., those don't work. Was able to eventually power down without doing a hard reset, and when I started the device up again, I could change volume and play/pause, but when I hit the Back button from the wps, it all slowed down and became unresponsive again.

One development in the weird random pausing thing (or just regular moments of silence that occurs at random times and the entire wps slooooows waaaay dooooown):
So of course it's happening again right now, because I have more than one file in a playlist, and that's when it happens. I was able to get it to power down just pressing the PWR/Hold button, but then it went into panic mode. So maybe this info will be useful.

Okay, I think I know what's going on with the random pausing and the wps slow-downs.
The files that it occurs on aren't being read correctly. On all of the ones that have had this happen, they're supposed to be at a 128 Kbps at a constant bit rate mode, but if you go to Show Track Info, all the at-fault files read 127 Kbps. No other files do this.
(Show Track Info: from the wps, press and hold Option to get the Context Menu, and then choose Show Track Info.)
Another thing that happens with these files is if they're rewound a few seconds (skip back), it often goes to a different (earlier) place than it should. That also happened with Rockbox on the Sansa Clip with occasional files, but that never had the pausing and slow wps issue.
I took one of those problem files and just sent it through Audacity, exporting it with the same settings -- 128 Kbps, constant bit rate -- and put it back on the device. Once I did that, the file didn't have the issue, and Show Track Info read 128 Kbps, not 127 Kbps.
So I'm nearly sure it's something to do with those files being read incorrectly. I've double-checked those files on my machine, and according to mediainfo (linux command line tool) they seem to be 128 Kbps, but just aren't being read that way by Rockbox. It could be a problem with the files themselves, but they're coming from some national broadcasters, so I'm assuming they're doing things well enough, and the files seem to be without issue when being read on a computer (i.e. no 127 Kbps issue). If possible, I'd rather not have to send files through Audacity every time I want them to work on this device via Rockbox.
So that's that.
