I've been trying to decipher this for a while, since the instructions are laughable

Yes and yes, the bell crank does alter the pedal ratio.. Five years ago when I decided to do away with the manual brake system on my BBC '71, I went through the same clearance and "appearance" dilemma.. After pulling my hair out I bought this "conversion kit" from Summit. At the time, they included a proportion valve. I see it's no longer included in the kit.

For me, with proper bleeding, it was a simple bolt-on and go procedure.
