You should be fine with the valvetrain componets you listed. If you have the money go ahead and swap out the oilpump and timing chain, I would go ahead and at least change the chain if you have some miles on the truck.
You can change the rod bolts with the motor in the truck. You have to move some stuff out of the way and drop the oilpan. This would be much easier on a lift than in the driveway though.
