http://mark-strong.com Widgets provide many of the items that you see in a blogs sidebar and with this tutorial you will learn how to arrange and install them. You will also find out how to use widgets in Wordpress for ads like Adsense and banners. Plus learn how to use them for an email capture form with your Aweber or Get Response autoresponder.
I'm not sure what you mean because the video is about installing widgets. But the plugins tab is on the left side of your dashboard right under appearance. If you click the arrow you will find "ad new" . If you click on that it will take you to a screen where you can search for and add new plugins. Hope that helps.
