Those are good questions.
1) What's the purpose of the angel statue in the Nibelheim Reactor? You know, the one Sephiroth rips off to reveal Jenova? I mean it must have somekind of conventional purpose (seeing all the pipes and shit), but it's also sculpted to this form.. Knowledge or thoughts on this?
Nomura's writing (or maybe it's Naora?) on
one of the sketches of this thing may offer some insight, but it's hard as shit to make out his handwriting, especially the kanji. I can make out some obvious stuff like ハーネス ("harness") for the statue's "hair" and what looks like メインパイプ・接続部 ("main pipe attachment component") near the bottom, but nothing useful.
I think I see the kanji for "wings" (翼
. It seems to say 翼Aパーツ ("Wing A Parts"?) for the large wings and 翼Bパーツ for the smaller ones. I see the word パイプ ("pipe") in there a couple times for the Wing A description, and the word ジョイント ("joint") under Wing B.
Actually, I think I can infer what the Wing B description is saying -- something to the effect of "Connects to the Wing A Parts at the joint"?
In the small illustration to the left, I think I see 背中へコードで接続 ("cord connects to the back") and 背中の受けパーツ ("receptacle parts on the back").
So, yeah, nothing too useful here.
The Crisis Core Complete Guide's Keyword section isn't much more helpful:
"
Jenova Doll
A metallic likeness of Jenova that was placed in front of her at the Nibel Mako Reactor, which Sephiroth destroys during the game. The details of how it functioned are unknown, but it is assumed that it helped to process and filter the sucked-up Lifestream."

2) The final boss battle. I'm pretty sure this one has been answered elsewhere, but "Bizarro Sephiroth"? How or why did he reform in to this shape? Was this caused by Mako/Lifestream? What is this thing actually..
"Bizarro" is a mistranslation of リバース. This could be transliterated as either "Rebirth" or "Reverse." The translators went with the latter, which they then localized as "Bizarro."
Obviously, it should be "Rebirth," as that's what is happening here. "Birth of a God" and all that (the song that plays for the battle). Sephiroth is being reborn into Safer Sephiroth, and you can actually see Safer Sephiroth emerging from this pupa-like thing that is Bizarro Seph.
This is more obvious in the concept art.
