1. No you don't get double the power. But you get improved performance. Usually at its best it will perform 1.5x the original cards capabilities.
2. SLI is a standard, much like ATI's Crossfire, implemented into certain motherboards to allow two GPU's of the same model to communicate and share their processing ability towards a common goal.
3. Yes you will need a new motherboard if yours is not SLI capable. As on a SLI motherboard there is physically another PCI-Express slot for another graphics card.
In my opinion it is not worth it, as you are better off just buying a single better video card then two lesser quality video cards. For now at least. But if you have the dough to purchase two 8800gtx's and run them in SLI, more power to you!
