Post installation

The site (http://www.hinterhofdesign.de) is up and running. No problems, no errors ... everything operating well.

But:

In the watchdog list there are lots of messages, that an anonymous user could not access several pages. This is (for these pages) correct though they are secured.

how would i set up a breadcrumb style of navigation at the top of each page, one that the further i went into a subject would extend further and update itself? any help is appreciated

I have set up 2 seperate rss feeds and they are working just fine, but having to update them automatically is becoming a drag. How do i go about setting up the crontab?

I saw in a different thread about this flat forum module. Looked pretty good and I was pretty impressed with a few of the demos I saw for it. It looks a lot like something I want it to look like. So I follow the instructions and install it to my test site. Only it doesn't work.

How can I create an account remotely? I have a database application on another server that needs to create new accounts for users.

One thing I've been doing (in 4.5) is using XMLHTTP to pass username and email address to the "create acct" page. This works fine, but is there a way to complete the process by setting the new user's password, rather than having Drupal email a randomized password?

I've read the forums and followed every bit of advice I could find to get drupal sending emails, but nothing seams to work. The SMTP module is installed and reports that the massage has been sent successfully, it just never actually arrives.
