Just two quick questions

I am doing a header for my blog site and it is coming along. My problem is that the design I am doing is not complicated but I need some help with. Now, I got this idea from a site and whatever. I posted my question on another help site and got some help. He did give me a copy of the .psd he did everything on. Now, here is where I am puzzled. I have a threshold part of the piece. But there is also a copy of the whitespace of the threshold. I know you do I believe Image>Adjustment>Threshold to get the black and white but how do you copy the whitespace. And also, there is a pattern overlay issue. On the .psd, it is checkerboard so would you have to make a pattern or is there somewhere I am not looking in Photoshop that has this done already as a pattern? Here is the .psd that I am using in reference to my header. Thanks!
