Providing you have the V8, I would think you SHOULD be able to swap the LS3. You would need a L92 intake manifold though. You will need to delete the VVT or get a L92 cam & vvt front cover. Either way, you will require some custom engine tuning. At least this is what I think. LOL.

Trans, this may be harder though. What trans do you have now?

Every thing in there now hooks rite up including the transmission and all sensors, the tuner will take care of the VVT if not already part of the ls3 any way, be sure to take the complete engine with intake manifold throttle body mass air flow meter and map sensor, motor mounts and water pumps will all bolt on but pay attention to location of alternator, power steering pump and AC brackets cause their position may vary. as far as the transmission find out what you have, if is a 4l60 or 4l65 is likely you could use the same hook up and computer.
Don't neglect a 3k stall converter while you are at it.
