I am going to dig up some clumps of tall fescue, then reseed it with a
lawn patch (seeds, foam, etc. all-in-one).

How do I prepare the soil?
Someone said "scarify" it.

Do I need a special tool?

To scarify the soil simply means to you break up the surface to help the
seed establish itself. In your case, since you are seeding patches where
tall fescue was removed so you can safely skip the scarifying.

BTW rather than those lawn patches a bit of triple mix and good quality seed
will do just as well, or perhaps even better.
