Recommendation For Keynote Presentation with Gen 4 iPad?

[rocknrollchef]

Hello, I have some quick questions if anyone knows:

1. My iPad is too old to download the current Keynote software - is there somewhere I can find/install an older version of Keynote?

2. I have a Keynote presentation (using my MacBook Pro), which features photos and videos. What is the recommend format to export this? Movie? PDF? What?

3. Is it possible to import the Keynote presentation into my iPad without having the software? If yes, how?

THANK YOU
