Yes, this workout program is very good and does show results in short time period. I personally have a friend who used to be over weight and now is in the best shape of his life thanks to the p90x workout. You can purchase the DVD's at the p90x website.

None. You get the nutrition guide, the workout schedule, guides, and worksheets. You will need to buy the chin up bar and dumbbells or resistance bands separately.

It seems like a useful system. You can find reviews from the amazon selling site here http://www.amazon.com/P90X-Hortons-Extreme-Fitness-Workout/product-reviews/B000TG8D6I
P90x is a workout system. You follow a box set of DVDs that vary by difficulty. P90x reviews would be what other (current or past) users think of the product.
To order the p90x program, one has to directly call the p90x company or order from their website. This is because p90x attaches a "coach" to the customer who is responsible for selling the customer other products and making contact with them.
Yes, but it would be wise to do lifting on a different day as p90x or else you will over train your muscles. For example, MON-LIFT TUE-P90X WED-LIFT THU-P90X FRI-LIFT SAT-rest/P90X sun-rest/P90X. Remember, rest is just as important as the workout.
The P90X workouts do really work. I started not too long ago and i have lost 19 pounds. You really need to try it.
