I have been looking a little at the <button> tag.

I am confused on how to properly use it. It seams that they are used within forms, whilst others use it outside forms. I also wanted to place a hyperlink inside this, but it is not liked very much from my validator. My question is how would you use them properly outside a form, or would you be forced to use an a tag instead.

Awesome CSS Buttons used both buttons and a tags for their buttons. They both used them outside a form, not entirely sure if this is for presentational purposes, rather than functional.
