 I would not attempt to use pliers or a bending tool, they will both distort the metal locally and damage threads.

For the front filter rim I would either use the repair tool you mentioned or a suitable diameter delron rod clamped in a vice to support the bent in rim while using a small hammer to tap the outside of the rim to restore its shape.

For the focus ring distortion I would disassemble the ring and do the same or make up a pair of shaped jaws to fit a mole grip to get in behind the rim and fit the outside of the undamaged part of the ring and use that to tease the damage out.
