Standard Archive Page vs Custom Post Type Archive

Hello There,
I've come a long way with this project, but now have to major hurdles remaining. I created a Custom Post Type (Projects), and need my Custom Post Type archive page ( to look exactly the same as my standard archive pages (i.e. I'm not sure what I'm doing incorrectly with that.

That said, I am also attempting to add the Custom Post Type into the Wordpress loop, so that on the home page that displays recent posts, it displays both Posts and Projects.
