I read your preferences and circumstances and agreed that P90X is as close to a jump-start as you're going to find that fits in with a busy schedule and a goal of general fitness and fat-loss. You can do this at home: no going to a gym, no traffic, no waiting on machines. It requires little equipment, which generally can be stowed away when not in use. And you're doing cardio but with a high level of muscular stress, which is (iirc) ideal for burning fat.
of exercise isn't all that essential, bearing in mind that form follows function. Anything you do that raises your heart rate and keeps it there for 30+ minutes will yield results. The key is consistency, and for that you have to go with something you WANT to do and WILL do day-after-day. Consistency in your program trumps any particular exercise in terms of solid, long-term goals.
Regarding diet: concentrate on vegetables and whole grains.
I hope this helps.
