Post installation

Did a number of searches on this but am a newbie here.

I want to change the background color in the header and I believe I've found where this is in xtemplate.css code below.

However I'm used to six digit color codes and the light blue of the header doesn't match what I get when I test #69c in another file for a background color. I see in other areas both six digit codes and these three digit codes. I'm sure I missed something somewhere. I'll do a search on google but would appreciate some help.

I would like to redirect .mil and .gov visitors to a page in a subdirectory that only they can access (that is taken care of) but then allow them to go back to the home page after they've read the secure page.

example:
.mil visitor to nsb.com > redirected to nsb/mil/index.html > selects a link back to nsb.com

I have a Drupal 4.3.2 running at home. Everything goes fine, except that anonymous comments simply disappear. If I set the anonymous user to post without approval, their comments won't appear under the article body when you try to read them. If I set them to post with approval, their comments don't appear on the comments moderation queue. What's going on?

If I want to divide up my web site into four sections and have each section have different menus, but all of the pages in a section have the same menus, do I need to have a theme for each section? Are there other ways to accomplish this?

Is it possible to use Drupal to edit and keep track of changes to Drupal code (themes, blocks, configuration files), or does one need to use a separate CMS?

If a separate CMS is used, are there any recommendations? I have FTP access, but not shell access to my web server?

Guys I seem to be getting a problem when creating content in this case a book page, the following message appears on the right hand side.

warning: pg_exec() query failed: ERROR: pg_atoi: error in "book": can't parse "book"
in /usr/share/pear/DB/pgsql.php on line 171.

user error: DB Error: unknown error
query: SELECT n.*, u.uid, u.name FROM node n INNER JOIN users u ON u.uid = n.uid WHERE n.nid = 'book' in /var/www/html/drupal/includes/database.pear.inc on line 89.

Any ideas?
