Love it! perfect for a paper wallet!

But I have a question...

I'm a newbie I'm still wrapping my head around how to use/save bit coin address via bit addresses

So I go to the site I generate say 1 paper Dr. evil paper it has Load & Verify and then a Spend one how do I associate this paper address with say my Bitcoin wallet I don't see where the private key is shown on the dr. evil money.

What would i use the load and verify for and how would it associate with the spend address or is it two separate "accounts"

I'm just confused on how to use it I would like to save my bitcoins on paper rather then trust them solely on the computer but i need a bit more help in understanding this treat me like a 2 year old LOL

Thanks!
