it doesn't really matter. if your battery runs out fast then you should charge it a lot.
No. It's impossible, unless some wonderful invention is invented.
When I plug in my laptop, it does not use the battery to run the computer. Instead, it uses the wall outlet to run the computer and to recharge the battery. So, by leaving my battery in my laptop when it is plugged in, I am recharging my battery and not running it down. If you take the battery out of your laptop and do not recharge it, it will not last long. The computer batteries that I know about can go from 2 to 8 hours without being recharged.

It can operate upto 1 or 2 hours only, before requiring a recharge.
It all depends on the brand of laptop that you have purchased and the type of battery that it uses. Your battery hours range between 3 and 7 hours depending on how good the batteries life is for that particular laptop system.
You can't. The cell phone charger needs AC current in order to recharge its battery. The laptop is incapable of producing AC voltages.
Extended battery life is where the Panasonic Toughbook laptop really shines, with 10 hours of battery use before a recharge is needed, or 14 hours if you get the optional second battery.
No. Leave it plugged in. Each discharge and recharge of the battery is a cycle and will reduce the efficacy of the battery. The battery will still age and reduce but a good computer will keep it trickle charged when it is at full capacity preserving or extending its life a bit vs full discharge and recharge every day.
You do not need to use battery. However, if you do use the battery, your charging habbits have a bearing on the battery life. For example, short recharge cycles may adversely impact the life. I think it is better for battery to drain fullly and recharge fully to use.

Apple does not recommend keeping your laptop plugged in continously as this can ruin your battery. Read more about this at http://www.apple.com/batteries/notebooks.htm
