Need More Power

Need More Power
I have a 2007 Sierra Crew Cab with a 5.3 and trailer pack. I would like more power to pull a 4000 lb 20 ft enclosed trailer. Anyway I was thinking of the following options:
1. Keep 5.3 and add a magnuson supercharger
2. Keep 5.3 and add a procharger
3. Pull 5.3 and replace with 6.0 or 6.2, what would be involved.
4. Pull 5.3 and replace with 6.0 or 6.2 along with 6 speed auto(maybe from wrecking yard).
I believe the last 2 would be easier due to wrecking yard available parts but what would be needed electrical/computer wise.
Any GM tech got a answer on how they would do it.
I would trade in but I owe about 5k too much and it is a loaded and slightly customized truck so I don't want to give accessories away in the trade.
Thanks.

I'd think it'd be easier just to drop money into your 5.3. You throw a supercharger on that thing, that'll be bout all the power you'll need. Or you could do a gear swap, put in 4.10s good all around gear.
