One option is to push down both mouse buttons to move and turn the mouse to turn your character. Then your other hand is free to use skills. I think many people who are very good at kiting use only their mouse for movement.
I completely fail at that method myself. I play on a laptop, and I have mapped the right/left strafe to the right and left arrows and turning to page up/page down (which are directly next to my arrow keys). That allows me to hold both the right strafe and turn left button at the same time to make circles around mobs at whatever distance i want, and leaves my left hand free to hit skills.
If you can workout how to use only your mouse for movement, in the long run that is probably most effective, but if not, play with various keys to see what allows you to use two fingers to strafe and turn, while leaving your other hand free to hit attacks. It will depend on both your keyboard layout and how you have your skills mapped, but eventually you'll find something comfortable.
