You forgot a couple steps:

1: install smcfancontrol
2: go to preferences and crank up your fan speed to max

I wish I was joking. It also helps to make sure you have plenty of air flow around the laptop. I stick mine up on some of my sons legos.

Really though you have the gist of it. There isn't that much in the stickies for us mac owners but there is enough information if you search and hunt-and-peck around.

One tidbit. You really don't "have" to copy 2 wow folders. Just go into the wow folder and copy the World of Warcraft app itself. Thats all you need to do - takes up 22mb or so that way vs god only knows how many GB of space. It seems to jump up every time I blink by another GB.
