For point 2, just spam long rests.
There is no reason to not spam long rests. Did your character stub their toe and lose 1 HP? Long rest. Did you use a worthless spell that you rarely if ever use? Long rest.
The idea that you are in a "rush" and need to conserve time is a lie. I did this mistake in my first playthrough but on my second I just long rested after every encounter, and instead of eating food or healing. And it felt like cheating basically but it is allowed by the game and works way too well. Only issue could be loading screens but even on a hard drive, not an SSD, it loads real fast.
