I’m honestly not aware of any plugins, but I’m definitely not the one to know all the best plugins out there.
As far as what’s in the theme and WordPress by default, you’re going to have to get creative with the design of your page and the elements you use on it. At your exposure you have a few things that might be helpful.
1. You can use the class “pretty” on an image to give it a frame.
2. You can use the class “alignright” or “alignleft” on an image to position the images to the right or left of text
3. You have the theme’s column shortcodes if you want to arrange content in various ways on the page.
