Swapping 99 Alero 3400 with 99 LSS 3800 s/c

[aleros_eat_rice]

I've decided what I'm going to do for my Alero is swap the motor with the stock supercharged 3800 series II from the 99 Olds LSS. I went to rockauto.com, and I can get a reman 3800 engine and charger for around $3k +shipping. I figure that this way, the engine is already built to handle a supercharger, and the engine itself won't need much of any special tuning.
I know I would need a few other things, like flywheel, exhaust, fuel pump, injectors and pcm programming.
What else would I need to accomplish this? Any help would be greatly appreciated.
