Hello and welcome to the support community.
What your looking to do is create a backup in the event of failure. First of all your fortunate to have Mac OS X 10.5 installed which gives you the time machine application. You can obtain or use a USB drive and set that up as a time machine. Any USB external drive would work (where it is mac compatible) I personally use this method for backup and restore. In the event your iBook hard drive fails, you can restore from USB drive you setup as a time machine.
The beauty of this is, it's good for future migrations in the event your iBook completely breaks and you have to buy a replacement. Here is some further information about Time Macine that might help answer any questions you may have. http://support.apple.com/kb/HT1427
The battery meter will change according to the use of the iBook. If your doing very little work and its set to the best battery performance, then it will show plenty of available time remaining. If moments later you open a number if application or do a number of tasks, then you'll see straight away the battery use time deprecate. This again may change if the task or applications you was using have been closed or stopped.
I would say from past experience this has been accurate. It also depnds on the quality of battery being used.
Hope this helps.
