Unfortunately modern automotive electrical systems are extremely sensitive so even what used to be simple add ons like new stereos etc can totally mess up the electrical. Of course the broken ground might also just be coincidental. I'd start by disconnecting everything you added to see if the problem corrects itself. In the short term a car that runs with now stereo is better than one that has an awesome stereo, but won't go anywhere. Unfortunately if something has fried as a result of all this you may need a technician to find it and fix it.
