I know it's 2013 and all, but I think that a 100% AJAX site with hashbang URLs is still "playing with fire" from an SEO perspective. It *needs* to be perfectly implemented to be successful, which may lead to it being brittle [en.wikipedia.org].
That said, if you are going to do it, then do it all the way. Even your home page should use the same AJAX loading method for it's content. This will keep that static content from being indexed on every page of your site.
*Btw, and this may just be a typo from your post, but if you are using an exclamation mark "#!" then the meta tag should have an exclamation mark in the content attribute, not a "1"
