Good that it works – I think you could replace get_links with wp_get_links, if you want to alter its behaviour in the admin panel.

As for swapping ‘Contact’ and ‘About’, I guess you’ll need to change the order in which the links are called in your theme’s header.php file.

Trackbacks and Pingbacks are explained in the Introduction to Blogging in the codex.

If you look at your code, the structure of the sidebar is a set of unordered lists (<ul>). Each item in each <ul> is wrapped in <li> tags. The My Links section you added, though, doesn’t have these <li> tags round each – add them in, and it should appear like the rest of the sidebar.

The css for your visited links is

a:visited {
color: #999;
}

and you can just alter the colour as you wish. This won’t affect things like post titles, though, which are wrapped in heading tags (e.g. <h2>). To change these you need to alter the color of h2 a:visited, and so on.

If by ‘post type A’ you mean ‘posts in category A’, then you might not need to use a plugin – some category specific PHP added to your theme might do it. See the in_category template tag codex page for an example.

If you look at the get_posts codex page, the first example there might be a good starting point, as it’s similar to what you’re after.

I just tried adding your feed to Google Reader, and it has titles in the normal way.

Consider using one of the available adsense-related plugins to do this.

You need to understand some CSS to ‘manually’ alter the width of the content. The easiest thing might be to search for another theme which uses the page space differently.

I reckon cleaning up the site’s validation errors might help solve the problem.

I think you need to use the show_post_count parameter. See the codex page for the wp_get_archives template tag.

My installation is in root.

Using this verbose htaccess plugin half-solved the problem; I don’t get my WP 404 page, but I do get the server’s own basic 404.

Are the URL details entered correctly in the admin interface, Options>>General ? You should post a link here to the site you’re talking about.
