Drupal 7.x

I can't seem to find any menu settings in Drupal 7 RC2. I go to admin/structure/menu and there is nothing there (redirects to admin/structure). I have cleared my cache but still nothing!

I just installed Drupal, got a little content up and found a couple of themes to try.

First I tried an admin theme:
Tao and Rubik for my admin theme.

That never worked and it messed up my admin so I would only see an error or blank page. I had to clean the cache tables and reset the theme via database to get the site back up and running again to see the UI.

So I tried a frontend theme:
Corolla

I get this error on the front page:
Fatal error: Call to undefined function render() in /themes/corolla/node.tpl.php on line 82

Hi
I have problem, I try add to my website animation from FlashXML.net. I add to file template.info this text:

scripts[] = banner/swfobject.js
scripts[] = scripts/banner.js
 

where banner.js content:

First, I know some of what I am considering is frowned upon so unless someone has a better idea this is what I'm looking at.

I'm new to Drupal, so please bear with me. I'm going to create a book as follows:
Book1
...Chapter1
......Page 1
.........Item 1
.........Item 2
.........Item 3
.........Item 4
......Page 2
.........Item 1
.........Item 2
.........Item 3
.........Item 4
......Page 3
.........Item 1
.........Item 2
.........Item 3
.........Item 4
...Chapter2
......Page 1
.........Item 1
.........Item 2
.........Item 3
.........Item 4

I setup drupal 7 rc2, set 'search form block' to region 'header'. Its ok displayed while i'm logged as admin, and is not displayed while just visitor. I did not set any permissions and roles for this block.
