Knowing a little about the way engines fail when they lose oil pressure, I'd have to agree... Rod bearings are probably gone, but mains may be OK. Either way, there's likely not a lot of other damage... Cam bearings can eventually go, but the loading is much less severe on cam bearings, so for a quick shut down, they're usually fine.
Pull the pan. Pull a rod cap and see what the bearings look like. If the bearings are still mostly intact, then the rods are fine and new bearings should do the trick. Do the same with a main bearing or two. You can plastigauge the main bearings to check them, but if it was run w/o oil pressure, I'd probably just replace them all anyway.
Most likely, the bearing bits are in the bottom of the pan, not the rest of the oil system, so you should be OK there too...
So you'll need all the rod bearings, and main bearings to do a good job. You can usually tap the mains around one way or the other (Opposite the tang) and replace them without removing the crank...
The only special tool you'd need is a torque wrench for the rod an main cap nuts/bolts.
