New rods usually cost close to "recondition with new bolt" price. Yes, you will need the flex plate, balancer, pistons, pins, retainers, a ring set, a rod bearing set to balance and of course the crank. Basically everything (or parts of everything) that rotates. They weigh it all to calculate the bob weight so they know how much to add or remove to balance the assembly. He is right on.
