Bent rear control arm on 1998 Volvo S70

So someone barely hit my rear right tire; there was no body damage, but the tire is slightly tilted. This is the FWD model. The car still drives up to 30 mph, but beyond that it's hard to control. I drove it to a shop and the mechanic said the control arm was indeed bent. When replacing this, what else do I need to replace between the control arm and the wheel in order to ensure a proper fix?

You'll need a 4 wheel alignment as well. Other than that you should be OK, but it's hard to say unless you can see the vehicle.
