Some of those translator notes... I have to wonder if you've read any chapters other than the ones you've translated. Regarding the ones I noticed:
It is incorrect that he can't level any more, at no point has it been stated he's max level, it's just that the amount of exp will be insanely high due to his high level and most of the things he's been killing have been at most a sixth of his level. Rather, why would you assume the max level is 310?
How is he discriminating for not mentioning male beastkin? the only ones in his group are female. He was obviously refering to Liza, Tama, and Pochi. Did you think he was saying he plans to open a dojo for only beast girls? I don't get the point of this note.
He didn't forget about how many skill points he got, he was commenting on how it only takes one point a level for him i.e. 10 points to max level a skill, while for others it takes far more. Iirc, ordinarily the cost doubles each level, which means it would take other people 1023 points to max level a skill. That is what he was saying is "unfair", that he may be one of the only people on the planet who even can max level skill, that's also why level 10 skills are so broken, because that's the type of thing someone over level 100 might finally manage to get if all of their points went into a single skill.
