Phil:
Here's some answers.
1) You seem to have three content sections, each with several pages. I'd make three clones of Tiny Content and name them "About PNINS", "Events" and "Teams". Then I'd feed the content using Tiny Content's editor, in order to build the navigation block. An at the end, I'd put the three navigation blocks together to form the complete left menu. This way, you'll be able to edit every page using Tiny Content's built-in editor.
2) The breadcrumb's not so easy. I've looked at some scripts so far without luck. The most promising one can be found in the snippets of XMDT, but has no decent instructions so I haven't been able to make it work. Sorry about this.
3) The one news item calles "Important news" can be deployed using the module Spotlight. The new version was just uploaded to the CVS yesterday, and it'll let you do this: select a story to spotlight or let the system pick the latest one, as you wish. Then, this spotlighted story will include the headline and the intro text. Optionally you can include a picture. You can also add more links to other news, et cetera. What you need is a "minimalistic" Spotlight module: just one story, just one text.
I hope this is useful.
Cheers.
