Looking for a Blogging add-on, couple questions

I've read about a couple of blogging options out there for zenCart (News & Article manager, and a wordpress add-on) with these two add-ons, do they work with your current theme, or do they come with their own defaults that have to be edited to fit with the rest of your site? I'm looking for something that would be similar to setting up something on EZ pages, but with some more blog-like functionality. Does anyone know if either of these 2 mods work this way, or is there one out there?

Here are the links to the support threads for some of the mods that may meet your needs.
