Do your best, Kogasa!

Scaring people for Kogasa's sake? That's sweet of you, Seki-chan :3

Translated as much as I can, but what does パネェ　mean?
I tried Google Translate and came up with nothing.

Imma guess an say something along the lines of a friend or neighbor but will wait for a moonspeaker to see how close I am

Google Translate isn't good for definitions, you want a dictionary for this. And edict says, "a lot; to a very great extent; absolutely".

The Firefox browser plugins Rikaichan or Perapera-kun (they're two branches of the same thing) are a useful way to get access to edict (which is a free Japanese-English dictionary that's used by a lot of dictionary programs because it's very extensive) from the browser.
