Templating? Help, pivotal descision.

Hey guys. I really need some template suggestions. NintendoLand is mainly an informational website, but I want to have a more community feel, and get into blogging, and posting lots of news. I want to switch to WordPress. However, look at some of our pages, they are pretty complex.

Like the Nintendo Corporate Structure for example.

How can I shift the site over into WordPress, and keep the layout on these pages? Right now I’m using phpBB templates, because a lot of the pages are similar, and I just draw from one template.
