What hack(s) do I need?

[cinq]

First off, nice site you got going there Danny

Well, this is what i do for my site and i will try to relate to your site and your content.

I use my own hack vbArticles for all my articles, and you could too, to house the articles under :
Pulsar info : history , technical and specs.
Just create categories, its run off vBulletin and just link directly to the articles on your menu home.

I use vBhome (lite) for the portal front, and with a bit of hacking, can display the articles on the front page of the site.

For your links section, you can use vbLinksDirectory ( which is now in version 2 but a new version is supposedly out for beta testing ..soon ). It is integrated with vBulletin too.

Sponsors page, would be rather static i presume as not much changes there.

For your gallery section ( events ) , you can try the freeware Coppermine gallery, i believe it has integration with vBulletin as well ( i personally do not like gallery's layout ) or if you want a paid solution you can try Photopost.

For the rest of the static pages, just include vb's global into the file, should run the headers and footers nicely.
