I guess you haven't read the thread, including the original post and the page you posted on.
The chat windows are in "Docks", so when I mouse over them it zooms in.
The bull animation on the top screenshot, which shows that drums of battle is active, is from the addon Power Auras. I also have it setup to show other various stuff like if Fel Armor isn't active while in combat or my pet isn't sacced. Everything else I think is self explanatory, but if not feel free to ask.
