Looking for plug ins for wordpress niche sites to make my content look more organized!

i was wondering for all you people that use wordpress, if you could recommend some plug ins that help organize the content on my pages better. Some niche sites out there organize pages by one topic. And i was thinking of just keeping a blog to post articles but to have other static pages to just show information that will not change as much. For example maybe a plug in that can organize image product information like a grid on one page so it doesn't just look like one big list.
