Once you purchase vbulletin, they have en extensive support system. They will tell you exactly how to do it. You can also submit a presales ticket and they will tell you if it is possible.

And vbulletin does have icons for your rep. I am sure you can change them to stars. You would do this via promotions, strategy would be reputation. You would then create ranks assigned to each of those promotion groups, and you would assign start to those ranks.
