Actually, NoScript provides options for white listing and plugin behavior in the client preferences.
If you click on the NoScript icon in the browser toolbar, you should see a drop down menu link titled "options". Selecting that will open the NoScript preferences pane, and from there you can configure virtually all aspects of the NoScript behavior. In fact, NoScript even offers a tab called "WhiteList" with many common sites included in the default distribution, such as "google.com", "msn.com", etc. So, you should be able to achieve the desired result from within the plugin settings. My testing was done within FireFox (which is included in the TOR browser bundle), but the same features exist in the Chrome version of the plugin too.
With regard to a more relaxed version of NoScript, you could try Web of Trust. It operates like a community managed blacklist.
