For sure you're going to be looking at some tough-to-bust nuts and bolts on an 04 that has been daily driven in winters. So 1/2" drive sockets and a GOOD breaker bar will be mandatory. A socket for the axle nut would be useful. A heavy deadblow hammer and some good prybars will probably be required at some point.
But for removing an entire engine, having a set of smaller tools is going to be useful as well. There are all kinds of little things that need to be disconnected, so small pliars, compact ratcheting wrenchs, and things like that are probably going to be needed.
Have you considered the minor refurbs that may be useful to do on the motor while it's out? Oil pump, water pump, belts, timing chain, gaskets/seals?
