Welcome to the marvelous world of computer animation. These programs really are amazing. I've only been doing it for about a month (actually--literally a month) and had never done any before so I was where you are now. It's a ton of fun and extremely addictive. :)
Here is a link to the product store:

What you will need will depend largely on what you want to do.
Here is a page with the official starter tutorials from iClone: http://www.reallusion.com/iclone/iclone_training.aspx
You will also find TONS of them on YouTube from users and there are other official tutorial pages as well.
Edited to add: Just putting this on here to show you what you can do even as a raw beginner. This is one of my dance animation entries, the latest I've done. It isn't perfect by any means, but as you can see, creating animated videos, skits or movies with this is not out of anyone's reach.
