Post installation

Warning: session_start(): Cannot send session cookie - headers already sent by (output started at /home/fielddy/public_html/includes/conf.php:88) in /home/fielddy/public_html/includes/session.inc on line 5

I'm getting messages like that on the top of my index page. I just installed drupal and i admit i don't have that much experience with this stuff but this one perplexes me and a friend.

Is it possible to let user to post content with the timestamp field editable by user?(ie. the "authored on" field) But without giving them the administer nodes permission.
It's pretty important to me as I would allow my user to make "future post"

Is it possible to fetch the links that reside in the weblink module to use in another application? For example, i would like to have a list of links of a specific category in my blog, located elsewhere.

I think it should be possible by querying the database. I'm no sql/php expert, so i don't know how to do that, any suggestions? Particularly I like to know how in the database the weblink is related to a certain category.

I cannot turn on the "Don't show banners" in permission. Any idea?

Thanks

This issue was discussed at least once before in this post, but I could not resolve the problem with the attempted fix that was posted. Now I am using phptemplate's Marvin2k clone, not the real marvin_2k, and the problem only manifests itself on when a story is displayed in "summary" mode. When viewing the full story the node image is displayed correctly.

I have been trying to get the permsissions system to allow me to bar access to the content of my site to annonymous users but not display a "404 Page not found error" as the front page. Any ideas. It could be a static page but then it would be content...

Cheers
