Helo Wei Lin!
The forward burst can be executed with what is referred to as a lead leg jam, which is where you lift the knee to about solar plexus height, fully bent with the toe of the lead foot pointed straight down. You use this like a moving wall to jam into the opponent's lead side to stop their advance or their attempt to kick. Yes, you do push off the rear leg when excuting the burst! The forward burst is also know as a burning step.
Th Jeet Kune Do hook kick is completely different from the tae kwon do round kick. As in all Jeet Kune Do kicks, there is no chamber of the leg and the foot rises to the height of the target and then you "hook" it into the target sharply, getting your power from the waist and the hips. The knee will bend only as much as is necessary for the foot to follow a straight line from the starting point to the target. This kick is MUCH MORE DIRECT than the tae kwon do round kick, and will definitely be more of a surpise to your opponent. The tae kwon do kick is telegraphic and easy to jam or stop kick!
In the backyard footage, Bruce Lee is doing a series of "pursuit" hook kicks, which is why the rear foot passes in front of the lead moving into the kick. It is a method of increased distance coverage at a higher rate of speed, which also adds more explosiveness to the kick!
Keep Blasting!

"What is Jeet Kune Do (JKD)? Chinese martial art, definitely! It is a kind of Chinese martial art that does away with the distinction of branches, an art that rejects formality, an art that is liberated from tradition." __Bruce Lee
