Will this bolt directly to my car without modification?

Yes. This bracket mounts at factory anchor points with no drilling or cutting required. Test-fit before final tightening to confirm alignment with your bumper cover.

Do I need fasteners, or are bolts included?

Fasteners are not included with the bracket. Refer to your factory service manual for the correct bolt size and torque specification for your vehicle.

Is this the only bracket I need for a full bumper cover replacement?

This covers the left (driver) side only. You'll need the right-side bracket as a separate part to complete a full front bumper install.
