Definitely give Demello (Jason) a call. He has firsthand knowledge of what works best and can give you good information and decent pricing.
If you're looking to lift the truck, a good combo is Donahoe coilovers in the front, with Deaver coil springs and Bilstein shocks in the rear. Jason has found this provides a nice ride along with good off-road capabilities for both the 4Runner and FJ Cruiser.
If you're willing to wait for an indefinite period of time, Donahoe might be coming out with some rear shocks in the (dare I say "near") future. Those would be comparable to the Bilsteins, if not better matched to the front coilovers.
