administrative theme

How far do you go with developing themes for simple site with a couple of pages?

I usually only import HTML and CSS files into Drupal tpl system and add those mandatory variables in page.tpl.php and node.tpl.php. I never edit CSS for admin pages (e.g. posting/editing node forms, tables, ...), because I use admin theme like Root candy and Administration theme with them I can make other pages like "/users/*" and "/user" to use admin theme as well.

I've been working over in the theme candidate for core7 area for a while focusing on a 960 based core theme and subtheme starter kit. In addition to this I've ported over an admin theme from d5 we've used internally for a while now to d6/960 grid. I would love to get feedback from the UX team on what is good/bad about it, and where it might be improved. Ultimately I'd like to see if we can get this into core as an administrative theme. Let me know what you all think, and how I can improve this.
