Do I need to press a new bearing onto the hub myself?

No. This assembly comes fully pressed and sealed — the bearing is already installed. You bolt the whole unit straight onto your vehicle.

Will this bolt up using the factory mounting points?

Yes. The unit is designed to use existing factory mounting locations with no drilling or modification needed.

What tools and hardware do I need to install this?

Standard hand tools and a socket set cover the removal and installation. Any hardware required beyond what mounts the hub to your spindle should be confirmed against your vehicle's service manual before you start.
