Between the two engines, providing they both don't have the same problems (and this is IF there's anything wrong with them but I don't see someone selling two for that price if they were both in good condition IMO) then you should be able to build one good engine.
From the little bit that I know (which isn't all that much), to do a swap you're going to need mounts, axles, shift linkage, ECU, wiring harness, and intake/exhaust manis. I'm not sure if that's all you'll need, but the smarter people will correct me if any of that's wrong =)
