The 2.3 oil pump swap you can do but not really necessary. It is a good mod to do but unless your looking to squeeze every ounce of power out of the 2.4. But if your plan is the s/c I would spend the money more on a very good polish and port job on the head. That would be better money spent.

Far as other machine work I would have crank cross drilled and even knife edged the throws. Go with the eagle rods and weisco pistons. Have at least the piston skirts coated.
