For NoScript functionality, there is a NotScript extension for Chrome.
If there is software that installed Chrome without asking, you should report this to Google. They don't like this sort of thing and might want to take action.
As for tab-management in Chrome, there are a number of different extensions for this. There is also the ability to display tabs on the left, in a menu, etc...
Finally, Chrome doesn't report information to Google unless you configure it to do so (i.e., search suggestions, etc...) Since the code is in the open, people monitor this very carefully.
