After you setup a new Drupal website, there are several things you can do to make administering the site easier and faster.

After installing Drupal, you should create an administrator role. This role will receive all of the permissions that you will use in your day to day administrative tasks. After you have created the administrator role, you should create a new user account for yourself which is different than your first (super user) account. The new user account can then be assigned the administrator role and you can use the new user account for all day to day administration. This strategy minimizes the number of times you will need to login as the super user, allows multiple people to administer the site, and reduces the risk of the super user login being compromised.

The second thing you can do is install the admin_menu module. The admin_menu module adds a drop down menu to the top of any site. The menu includes all administration links so you can access any portion of your site with a single click.
