Under your list of things to cover, I think it would be cool if you/they covered the actual video/audio option that you can choose from inside WoW. View Distance, texture, Direct X, etc.
What are the best setting that get the best look for the least requirements? I swear that on my computer it runs smoother when everything is turned all the way up (besides ground cover), than when i turn everything down. Which options don't have much a an effect on your FPS, and which ones make a huge difference?
There are a ton of options inside the WoW Video/Audio interface, and Bliz seems to keep adding more. Some people may not even know that you can play in a Windowed mode to make it easer to Alt+Tab out if need be.
