Post installation

First off: Can somebody confirm whether I'm posting this question in the right forum?

I'm getting a drupal site up and running. I set up the event module, an events flexinode, and a block to display upcoming events as a list. I was very proud of myself for getting it all to work properly, without having to ask my server dude anything, and purely by reading existing info/forum stuff off drupal.

Hi,
I'm running drupal 4.7 and I can't seem to disable the "create content" link for anonymous users.
I've put the "create content" menu under the Admin Menu, but it still shows up when I'm logged in as a guest.
Am I missing something?

I am looking far a iCal/Calendar app that can be integrated into drupal for a community website i am finalising (unpaid). I want to integration to include a 'latest/recent events' block and have this link to a node.

I had installed WebCalendar externally, though have recently found PHP iCalendar which is a lot more aesthitcally pleasing and i have seen in integrated into some cms sites. I have also come across reference to a number of others.

Well, I love the module! makes very nice dropdown menus. with a little css tweaking I think it can do and look like anything. (Kudu's to the coders)

I do have a small issue.

HDI make the child menus go on top of my sidebars and content? (using modified friends electric, and drupal 4.7.b5)

(http://drupal.totaldestruction.us) if you go to the menu item on the far right, (blogs) see how it drops behind the right side bar. Any Ideas? and can it be done in the css?

Thanks

I am using a node_form function in my template.php in order to lay a node form that i have customized out properly. I would really like to write a bunch of checkboxes in a table. how do i combine form_render and theme_table to do that?

Why do I need to have a prefix for my database tables on a multi-site install?

In my settings.php I have this:

$db_prefix = array(
  'default' => 'main_',
  'attachment' => 'shared_',
  'authmap' => 'shared_',
  'banner' => 'shared_',
  'banner_term' => 'shared_'

What will break or not work if I didn't use prefixes and still had multiple sites?
