Problems With Inventory, Images....help please?

[Turtlestork]

Ok, so  set up a virtuemart site for my Uncle's business. The thing is we have started experiencing a few issues.

Inventory-
We sell different types of jerseys. The thing is, with jerseys, one player's jersey comes in multiple colors as well as multiple sizes. I used the attribute/property options to makes these selectable. However, I don't know how I specify how much of each product type I have in stock. I can put the total number in stock, but I obviously have different sizes in that. How do I do this?

Images-
I tried to add images, and there appears to not be an "upload" button. How does this work?

Paypal-
I selected paypal as a payment gateway-however I don't know how to set it up so it outputs to our paypal account directly. is this possible?

Thanks

2.When you've added a product click on media icon in product list to add more images

Ok, so so far I've only checked out the inventory thing, and this is what I perceive from it but I want to be sure...

This is the order of organization:

Products > Items > Attribute

Ok, so product would be like "Favre jersey", Item would be "purple" and attribute would be "size". I'm just really confused how this all works, and how this is all defined. Can someone clarify this for me?
