When you go to "my account" I see they added checkboxes for what needs to be completed. is the "Redeeem a product Registration Code" (third from the top) the code I will receive (hopefuly soon) for the pregame access or is this the key i had to enter when i purchased my preorder and registered it? The reason i ask is because it is not checked off and I'm hoping somethign didn't go wrong when i registered my preorder a few months ago.

That is for your product regristration code, not your pre-order code. You'll get that code when the game is released, either in the box or on origin dpending how you bought your game.
