Yeah that only applies to his mind/soul, so unless you have fuckery regarding anything about those you're in the clear
It's not a MASSIVE Buff/Debuff, but it's enough to be somewhat relevant(like, it's 20% or so)-- though I should note that if you get him away from the Great Book of Grudges it's a non-issue because Thorgrim doesn't generate the buffs himself.
As for skill, this is the same guy who goes in and out of millions of trained soldiers without being touched once, and there are numerous stupid army solos below Thorgrim in the skill chain of similar absurdity(we have fodder who make rivers of blood from massive monsters and trained soldiers for gods' sake), but Dwarfs aren't exactly known for stellar agility and dodging, so it's largely fine until you realize Thorgrim knows full well how hard his armor is to get through, which makes him a problem because he's liable to Senator Armstrong attacks that aren't directly to his head, and even then he'll try to block headshots(pretty useless against AoEs though)

Isn't something to worry about if you're even asking this question.
Not certain, this man makes himself stronger and makes his opponent weaker and slower as well. That's a significant buff and debuff right there. His stamina is enough to fight for weeks without rest, which is greater than anything in MHA. I have no idea how effective his abilities are, and I'm also incapable of judging skill as well.
