I saw the large banner at the top reading "DO NOT USE THIS TEK FOR ACACIA EXTRACTION!." and assumed it was for MHRB. I have quite bad ADHD and I can frustratingly miss details even when re-reading multiple times, and given that context I did not parse that the tek then says "2 kilograms of DMT containing plant material (Acacia Obtusifolia bark will be used here)". I assume I am misunderstanding something, but I'm a bit confused there.
My best guess is that the author did use Acacia, but a significant number of other people later had trouble using the tek for acacia, which led to the warning being added.

It is recommended to do small batches, especially for the first few times. This has several reasons. For one, extraction efficiency goes down with size because the ratio of contact surface area to volume gets smaller. In other words, it is easier to do well with smaller batches. And maybe the main reason is that if all goes wrong, you lose less material.

Upon basifying, a shocking amount of solids appeared. I would estimate I had roughly a half cup of plant gunk appear out of 800mL of acid solution. Would this be due to using far too much MHRB for a recipe of this scale?
That's probably tannins. I don't think there's a way to completely avoid it, but using more water relative to the amount of bark makes it less of a problem.
For 2), I think the separation funnel is only really useful for steps that involve no solids. That could be a defat before you basify, or a backsalt from the NPS, for example. I don't think there's use for a sep funnel during the NPS pulls from basified soup.

Nowadays we recommend not to shake, because that carries significant risk of nasty emulsions. The method i hear recommended most, is to use a bottle, and gently roll it back and forth over a flat surface, then let separate, and repeat that a few times.
For 4), emulsion from acid defat is probably not worth saving. The naphtha shouldn't contain any DMT in that step, and the amount of dmt-containing water in the 'skins' of the bubbles shouldn't be a lot relative to the entire volume. In basified pulls, it may be a different story. One thing i found to work pretty well, is to force the emulsion through some sort of filter, eg. a cloth. That has helped me recover at least some NPS from emulsions that didn't wanna clear up any other way.
