Finally finished the chapter…
I don’t think anyone’s answered all of @VikingSchism’s questions yet:
6%
I struggled with this one as well…it’s pretty hard to unpack the grammar:
東条さんの家は、 → topic = toujou’s house
こころの家とほぼ同じ間取りの家が → more or less the same floorplan as kokoros but
東条さんの家仕様になっている → made like toujou’s
という印象だった。 → gave the impresson
仕様 means way/means/method and になる is “to become”. I found this example on nihongomaster which helped piece things together:
全てを考慮してもやはり勝てない 仕様 になっています。
All things considered, it’s set up so it isn’t possible to win.
so basically I think it’s a way of saying that something is set up/designed to be a particular way.
in this context, 東条さんの家仕様になっているという印象だった is saying that toujou’s house gave the impression that it was the original, and kokoro’s was a copy of it.

pretty much agree with what @Shadowlauch said, except for this bit:
身を屈めて自分 refers to kokoro here, and the whole clause is the object of 覗く - the bully was peeking at kokoro who was bending over (屈める can also mean bending your knees/squatting, which makes more sense to me).

I know @Shadowlauch already answered this one but I’m gonna do the breakdown anyway for my own sake because I got a bit confused well.
東条さんが本当は → toujou san was really
**** 先生たちから → by the teachers
**** 自分に会ってくるよう、に話を聞いてくるように → to meet me, to talk to me
と言われている かもしれない → maybe was told to
ことについては → with regards to
that’s a hell of a sentence 
―そう言われてるのにもかかわらず → despite being told that
彼女がそうしないでいる可能性 → the possibility that she wasn’t
については → with regards to
考えないようにする → she chose not think about
this makes the 6% one look so easy…
whaddup! been a while yeah (I didn’t read haruhi though
). I basically lost all motivation to do japanese over lockdown, but I’m picking stuff up again 
good work 
I’d kinda worked out that it was at least 6 months, but I hadn’t narrowed it down that much
