Well, I just installed the Warcraft Logs desktop thing via (ick) Overwolf, and I have enabled Advanced Combat Logging.
Now I just need to get the gumption to type /combatlog and do stuff.
Edit: Well, I did a LFR Gallywix and uploaded it. Not sure what to make of it, because that is a WHOLE lot of data and information. I really like the Replay function, that will be fun to look at.
