Utgarde Keep: The Keep (heroic)

I've been trying to get Fuzzyboy to tell me, but I think he's pretty busy. Does anyone know what add-ons he's using?

I'm assuming Pitbull.
I'm very curious about the grey bar... that seems to make everything look clean
What add-on is saying "xxx is ready"?

Otherwise, does anyone modify their chat box? I don't like the blank space where input it typed, which is only displayed when actually typing. It would be nice to have a different looking scroll tool instead of the default arrows on the side.
