I personally hate removing the card because I am convinced that someday I will bend a pin.
The only precaution I take is that I always connect the cable to the camera first, with the camera off, and then turn the camera on only when the cable is plugged into the computer. I reverse this when removing the cable. This is probably needlessly neurotic, but I do it to avoid any risk of a spark.
