Everything above is correct. You'll need a RWD starter (or swap the nose and starter drive from your old one onto the high torque Toro starter), A-body manifolds or headers, and correct motor mounts. Also, some of the Toro accessory brackets are different from RWD brackets, but your 350 brackets will bolt to the 455 as the brackets have two sets of holes. One subtlety is that the water pump must match the pulleys and brackets, as the A/C pump is longer than the non-A/C pump. Also, be aware of the spacers on between the PS pump bracket and the block.
As for the motor mounts, DO NOT buy "455" mounts. Just reuse the 350 mounts. These will bolt to the 455 (use the rear two of the three holes on each side of the block) and it will sit at the right height when mated to the 350 frame mounts in your car. Don't worry about the notched valve covers, you don't need them.
