   I'm just looking at my activity monitor and see that coreaudiob and WindowServer are consuming 4.6% of my CPU (each) - What are those, and is this normal?

   I believe they are the audio service and the OS's graphical interface, and yes, their CPU usage is perfectly normal.
   
   Not that a simple Google Search couldn't have told you otherwise, 4.6% is next to nothing.
