Electric drills are faster and more convenient, but not better than using the hand crank supplied. When extending the jacks, you want to "just" take the weight off and never try to lift the unit. It should be levelled first side to side using boards, plastic levelling blocks, etc. The X-chocks definitely help in stabilizing things as it is more difficult to prevent the small amount of back and forth rocking you get when using regular chocks.
