Chrome Plugin - Screenshots captures and more...

I need to create a Chrome plugin that will recored a series of websites, take screenshot of each website, get the urls to any video files, and then store those page links, screenshots, etc... to one of our databases... Here is the process: 1st) When someone installs the plugin, they would enter their info to our database (username / pw). 2nd) when they go to a website they like, they would click the "record" button on the app, then it would record each of the pages they go to in the session, take pictures of each page, pull links to videos, etc... 3rd) the person would end the session - and links to the pages and other info would be posted to our online database.
