Answer 1

Drop your knees a little when you punch.  Adds your body weight to the punch.  Also, twist the wrist a little.

Answer 2

Since your question is posted in the Cleaning & laundry section I'd say use a sponge.

Answer 3

bend you wrists, do not hit your target dead on, hit through the target, follw through, remember all punches origninate in the hips and feet, you should not be flatfooted when you are sparring
