front brake pads and rotors. are there bushings to be replaced also?
No bushings need to be replaced - unless you have worn bushings somewhere else unrelated to your front brakes.
But bearings yes, you’ll need to install new front wheel bearings with the new hub & rotor assembly. Front wheel bearing adjustment setting is 17-25lbft, back off 1/2 turn then retorque to 10-28ibft.
