Drupal 7.x

So I just installed a nice, fresh, sexy version of D7 on my localhost, and have been playing around with it quite a lot. But I've been having some problems.

In d6, if I want to override a template for example override page.tpl.php to page-front.tpl.php all I do is duplicate the file and rename it.

I'm having issues setting up my breadcrumbs. I have pathauto installed and have set up the page hierarchy as I wish.

I also have a main navigation menu in the correct order.

It goes roughly like this:

Home
About
-About
-Clients
-Services
Work
-Design
-Illustration
-Web
Stuff
-Blog
--Projects
-Comic
Content

I have a taxonomy vocabular with three terms. Each of my content types have a taxonomy reference field allowing one to link one term.

Now I want to display that taxonomy term in my node.tpl.php but I cannot find a solution!

Please help.

I downloaded Acquia Dev Desktop and then decided to uninstall. When I uninstalled I lost everything on my desktop and documents folder. I had not backed things up in a few weeks. What happened? I am in a panic, I had all the info on web site for clients. I know it's still on the server, but what happened to everything?

Please help.

I have a site for a firm with a handful of partners and they each have their own clients. I need to set up the user registration page on their Drupal site so that the client can choose who their partner is, and once the registration form is submitted, the selected partner gets notification, as opposed to the main admin. I also need the back end set up so that when the partner signs in, he can see a list of his clients but not any clients for the other partners. How can this be done?

I just installed Drupal 7 and I'm customizing a Zen sub theme.

I want to style the menu in the Navigation Bar to have a solid color background that changes when active, hovering, etc. Very simple. I put my changes into directly in the navigation.css file of my sub theme, and it worked great ... except now in the Drupal user menu at the top of the screen the "Home," "Dashboard," "Appearance," "Modules," "Reports" and "Logout" links are displaying the same background color as my Nav Bar! "Content," "People" and "Configuration" remain unaffected.
