Drupal 7.x

This should be easy and obvious but I can't find it.

I can go to Administration » Structure>blocks to limit access to blocks. But that seems to apply only to the home page.

What about the other pages.

Currently ANY user can click on a menu item and get directed to the page of his choice.

In searching I see some modules for pre D7 versions; but not for D7.

There's gotta be a way??

Hi,
I am new to Drupal, but i am having a great time learning it.
I am trying to develop my web page and I am having difficulty in creating my front page header.
I was able to change the title and the logo of my website but i have a small problem. When I insert the logo in will extend the header down ( it becomes wider) . When I saved the title it moved it away from the logo to the middle of the header.
How can I have the title just after my logo ?
How can I increase the logo dimensions without widening the header on the front page.

Hi to all,
I'm building a site where I've to store some sensitive data in external database.
I'm trying to figure out how to store these data create with CCK content type.
Can anybody help me?
Thank you.

I'm working with an up to date D7 installation. No additions - only the packages that come enabled by default.

What I've done is written some article pages on various topics and set the URL Path Setting to give each one a name, different from the nodeNNN name it's assigned automatically. The form of the names I use are topic/title, e.g. tv/thenews

I have also created some menus, one for each topic and I've added links to the relevant articles. Where the form asks for a Path I've used the URL I assigned when creating the article. The menu picks up the correct article and it can be accessed successfully through the menu.

The problem I have is if I make an edit to the article. Choosing Edit from the article's page I have noticed that after I save the edits, that page is no longer present in the menu and it's menu entry has been moved from my specific menu into the Main menu.

I have on my website a block and the content of that block has to change every week. I have a node to make the content for the block. So I can prepare 10 or 20 items.
Is there a module which could automate this? Depublicate the old one and publicate a new one.

I'm working with my first D7 for-fun website to get the hang of things (made a few D6 sites). What are your thoughts/critique on getting the following to work nicely together?
