When there is a combination of punches transition has to be brought into the equation.
As in what is the best way to transition from punch to punch.

Balance is key.
Defence before during and after the combo/punch is key.
and Timing is paramount.

Smoothness of technique is your speed.
Getting the body mechanics right is your power.

Practise on a heavy bag, focus mitts and with big gloves with a partner building up to isolation sparring then full sparring.

Thank you finally explaining to the masses what rolling with the punches means.

Great advise that all punches start with the feet, even in boxing good feet beat good hands, because good foot work get you into and out of range (without getting hit), determines the power and angle of attack. When watching a orthodox vs southpaw match the simple feat of keep their lead foot on the outside is dominant.

The difference between stepping with a jab and rotating the front hip is that you have to be in range already to do the later, if your opponent is any good you wont be when your punch lands.

To add to what you said about rotating you arm while punching, this has a number of benefits for attack greater power as you said, by rotating the fist it gives better penetration of the opponents guard, and for defense it also keeps the elbow tighter to the body protecting it at the start of the punch, and automatically lifts the shoulder to protect jaw and the forearm the face while punching.

Looking forward to the future posts on hooking and uppercut, these were taught to me integrating the movement from your defensive video and with the advise that they should be kept as tight as possible and as far as rotating the body with the punch, if you miss and with your fist you should catch with your elbow (not for use in the ring of course) but no farther.

Keep ‘em coming!
