Generally speaking, installing and having an installation of Wordpress is pretty simple. However, my advice would be to keep things as simple as possible, especially since it seems you guys are starting out.

For the frontend, I'd recommend either just having very thin pages in your Rails stack that are fully or at least heavily cached that then ping your API, or relying on something like Jekyll to generate static pages that then do the same.

Eventually, when the project becomes larger and/if you start feeling pain points, you can abstract this frontend layer away from the stack into its own little app. You could also make it its own little Rails or Sinatra app that just serves basically HTML (again, heavily cached, since the dynamic content will come from the backend). I keep recommending keeping it in Rails or Sinatra just so you can use some goodies like layouts, easy caching infrastructure, you're already hosting rails, the asset pipeline.

As for your marketing site, I'd go for something that's hosted elsewhere, like Tumblr if you need a blog, etc. Just try to minimize the things you need to host and support yourselves.
