Companies that sell exercise equipment, like Nautilus, are obviously going to tell you that their equipment is better, but any aerobic exercise that gets your heart rate up is beneficial. The only drawback would be the impact on your joints, so consider this if you have certain restrictions.
Yes. Lots of quick sprints, shuffles, and jumps really increase the heart rate, which is the point of aerobic exercise. Plus, this type of stop and go workout is similar to an interval workout, which is a very effective type of conditioning and fat loss workout.
A home exercise bike is like any piece of workout equipment. If you don't use it you won't lose it. Bikes are a great workout for the legs and if you push it can give a good cario as well. Don't forget to pump some iron to keep the body in balance.

Depending on the results that you want for your body, this will depend on the exercise you choose, if you are looking for tone and strength Pilates is the best exercise.
Not really. Training for competition might require some running or jumping, but few fun jumpers bother with conditioning. Skydiving itself is tiring, but not really all that aerobic.
I am not sure if exercise bike workouts are really advisable for laps. You can search for that online or go to the gym and ask other people what they think.
There is no single item that is essential for a home fitness center-- nearly any exercise can be done without equipment. However, if you want equipment, you should have at least one cardiovascular exercise device (treadmill/elliptical/bicycle) as well as a small variety of weights for strength training.
You can find some really great deals on equipment by going to www.craigslist.org in your area. You can also try Ebay for good used exercise equipment. You can www.craigslist.org in that area for people selling used exercise equipment. You can also try Amazon.com and Ebay.

Exercise equipment is handy and easy to use. You should always read the manual for safety reason. Once built, you really don't need to maintain them that much.
