How do I move pictures and videos from one iPad to another?
This depends, do you have iCloud? as you can sync through iCloud. 

You can also configure all the settings in iTunes. So you can import all the images into iTunes, once they are there you can connect the other iPad and sync them.

If you do not want to keep the iPad 1, you can just connect it to iTunes, sync it and then connect the iPad 2 and restore it from the back up of the 1st iPad.
