I also run 6k RPM for when I have WoW up. It runs very smooth, and the system stays VERY cool when I run on that setting. Granted, I have my graphics turned down to about middle of the road and I use a
Belkin Cushtop when I use my MBP on my lap. Gives some hight as well as keeps the heat off my legs and lets a little more air flow around the computer.
