1995 Chevrolet Beretta Wheel bearings/ Control Arm

I just put 2 new tires on the front of car about 2 weeks ago and now they are already bald around the edges. I cant seem to figure out why the tires keep going bald? I believe my car needs new wheel bearings and I was also told a control arm as well, But someone else said it could be just the bushings in the control arm, how can I tell if its just the bushings? When I go over bumps it sounds like a popping sound, Im not sure what is going on? I think I need a lot of front end work done to my car. Could u maybe give me a few pointers on what it might be? Also when I turn on the AC/ Heat or any of those controls a fuse blows that makes the gauges stop working and the head lights go out, what could be causing that?
