Good going so far Andy.

I recommend changing what buttons are shown in TinyMCE, add the unlink button (link button not working), remove all the table buttons, add format pulldown, and clear styling button. Also you don't really need the output Path to be displayed. It's best to simplify the controls as much as possible. Remember that you can have a different set up for the admin role (create an admin role in admin->access).

These podcasts from Lullabot are also very useful:

By the way, IBM just picked Drupal as the best open source CMS:

Looks like they've adopted it for internal use as well.

Also Forrester Research has published two reports on Drupal:

Exciting times in the world of Drupal!
