Dent and Scratch Repair

I got a dent and deep scratch on my car, below are the pictures:

The scratch lines look so white, does it means the scratch is deep in the primer? Do touch-up paint and polish fix it? Should I follow the "Paint Polishing Clinic" in autopia-carcare.com? How to fix the dent? Any DIY way? Does Ding King dent remover work? Or going to the pro is the only way to get that fix?



Thanks in advance.
