1. Digistore is the component itself, you must get it if you want to have the store. Digi mambot is optional, you can get it if you want to add "Add to cart" to your joomla pages.

5. I don't have an answer for that yet. We're currently working on other features.

6. Yes, it's $39.95, click on buy now button and then "digistore add ons"

7. You have till tomorrow night.

I also get confused about this but I think the logic is that you need the basic Digistore component and then can add on payment plug ins and other mambots as you like. Then equitation is like this if you want to calculate and you can use this for only one domain not on one server, files encrypted. So that means you can not use this as you belive "used over and over on any multiple websites" or your web server.

I dont know what that "more" is! 

So I have to have the Digistore before I can buy the mambot?

The site does not make that clear at all for new people. It sounded like you can just buy the mambot and use it.

That is why so many questions about it.

Next question is this:

What can the Digi mambot do that the Digistore can not do?

The mambot's only purpose is to allow you to turn regular article pages into product pages by simply adding an "add to cart" button. That's all. The digisotre does the real work, so you must have that.

Authorize plugin has been available for a while now, it's available under "digistore plugins" category.

No you can install the plugins on multiple sites, no problem.

The difference is that one supports 2co which is similar to paypal and doesn't require you to have a merchant account and SSL. Authorize does require these things, so if you don't have them -- don't buy the authorize plugin.
