Clef Changes Needed

[JDMEK5]

So I've just finished "Bilocyte" from The Legend Of Zelda: Skyward Sword, but there's lots of places that would be cleaner if there was a clef change or ottava marking.
So that's why I'm here. I'm wondering if anyone could put those in for me.

R.H. should be bass clef through measures 5-8,
Maybe an ottava bassa in the L.H. through measures 25-28,
And I was sorta wondering if someone could fix that derpy right hand in the second last measure. For some reason, it keeps crunching itself up.

Wasjust about to do this, but only have 2011... But this should really go here.
