Ubuntu – Help with LAMP sever

Firstly I followed the instructions on the following site to install the LAMP server:

http://www.multimediaboom.com/how-to-install-lamp-server-in-ubuntu-11-0410-1010-04/#comment-48391

step 3: go to http://localhost/phpmyadmin
This did not work. It came up with a 404 error at first then after running "sudo ln -s /usr/share/phpmyadmin /var/www" it came up with a 403 error and said "Forbidden: You don't have permission to access /phpmyadmin on this server".

Then the last step was to make a simple php file and test that php was working. I could not save the file into /var/www/

So to recap:

1. How do I get around the 403 forbidden error for phpmyadmin?
2. How do I save / copy / make files in /var/www/ when it is owned by root?

EDIT:

I have managed to save the test.php file into /var/www/ by launching gedit via the gksudo command. When I go to localhost/test.php however it downloads the test.php file instead of running it on the server.
