Stretching (static & dynamic)

Strength (maximal strength & explosive strength)
Balance (one leg and one arm drills)
Energy System (running and sprinting)
I agree on this.
I believe you will get much better instruction and progress much faster if you have a good coach who can show you how to do things and give feedback instead of trying to learn from a DVD. And even if you would learn something from watching a video, you would need sparring partners to turn the theory into practice.
Then again, boxing is actually cheaper than a normal gym or health club membership at least where I live. If money is the issue, maybe you could get an extra job and pay for boxing classes? I can guarantee that it will be a great investment
