Hm. I see:

Pitbull / AGuF for the unitframes. (pretty sure its pitbull though)
Mik scrolling battle text for the 'xxx is ready' + other text that is scrolling on the sides
Panel (grey bar) could be either eePanels2 or its current replacement KGpanels
elkano's buff bars for buffs
simpleminimap / chinchilla / sexymap for the mini map

edit: for chat box I personally us chatter. but it uses either default arrows or mousewheel scrolling. o.O; prat hates me -.-
