Questions about theming a node
Take a look at the default node.tpl.php. You'll notice that they render the content with render($content).

I've never used Contemplate, but if you install the devel module you can then use the dpm() function to take a look at the variables in detail. Try dpm($content), and you see all the content that you can render, or even use the hide function to remove content. For example, you can use hide($content['links]) prior to render($content) and the links will not be rendered; you can display comments with render($content['comments']);. Don't forget to print the value returned by render(), as render() returns the HTML markup used to render the element passed as argument to the function.

You can easily render the image field with render($content['your_image_field']).
If you are using the Countries module, then you can control what it is displayed in the content types display on admin/structure/types/manage/your-content-type/display, and simply render it like you do with the rest of your content.
