Theme Designer should be in the "My Tools" menu in your toolbar at the bottom of the screen. It's also here.

In terms of the menus, you already have some of those things (like the photos), but you can add whatever you want here.

Your template is using the images properly, but the one you added is not uploaded to the wiki. So you need to go to Special:Upload and upload it to that file name. Or you can change the name in the template to call another image that is already on the wiki.
