I went to change the lightbulb in the garage and the entire socket came out.

I bought a new Porcelain Ceiling Lampholder with a Grounding Outlet, but it looks like the previous outlet did not have the grounding part, so I'm wondering if I can still use this device.
The old one only has 2 screws for the white and black wires

The new one has a third green screw for grounding.

So did I buy the wrong one? If it's the wrong one can it still be used? Do I need to buy one without grounding? Also, I've never done anything like this before, and I don't have any gloves, if I just switch everything in my fuse box, I should be able to replace this with no shocks, right? Or should I just call an electrician?

Do you have a ground wire in the box? (bare or green). If so, connect it to the ground terminal on the fixture. If you do not have a ground wire, just connect it like the old one,leaving the ground terminal empty.
Turn off the switch that controls the fixture before you replace it. If you want, find the breaker and turn that off too.

one more q.

Awesome, thank you. One more question. I watched a video on replacing an outlet, and they cut the wires from the old one, stripped the wires again, and connected them to the new outlet, can I just unwrap the wire around the screws and rewrap it around the new one?

Yes. That would be the preferred method.

Only reason I would see cutting the wires off an old outlet is if they are back-stabbed. I just replaced a bunch of outlets in my new house and all of the outlets and switches were back-stabbed. In your case where you are dealing with a screw, just un-screw it and attach it to the new light.

Make sure the loops on the wire ends wrap clockwise, like a backwards question mark. That way, the loops get tighter as you tighten the screw. (It's also required by code.)

I also see that you've purchased a socket with a three prong outlet on it. That third prong really needs to be grounded. I'd take that fixture back and find one with a two prong outlet (if they still make them), or a plain socket like you had before.
