How much money are you willing to spend?
As VA, said I'm going to be camming my PW shortly (just waiting on my valve spring removal/change tool). I am going with a KRC 210X which will easily give you the 30+ ft-lbs of torque you are looking for. Take a search around the different forums and you will find vid and commentary on how torquey this cam is. I was going to pull the heads and mill them .030" to bump compression a little, but I've decided to wait until I see how the cam acts, and do progressive changes so I have a feel for what has worked. Just a cam swap like this will only cost you ~$400 for all the parts (I bought a used cam for $250).
If you have a few grand that you are willing to spend, by all means a SC would be kick ass. I personally don't really like the idea of a boosted heavy ass trucks unless they are diesel, but that is just me (unless you have forged pistons/rods I wouldn't want to run above 6-7psi, without hurting reliability). I'm sure there is guys out there that have done it with great success, it's just not for me. Also I don't think there is a specific bolt on kit available for the 05, so I'm sure a fair bit of fab work will be involved. If you do go this route, a whipple/roots style would be best over a centrifugal setup.
Lastly as they always say, there is no replacement for displacement. IMO if your looking for a real kick in the pants, I would look into building a stroker motor. The stroker will give you the torque you are looking for, and still have the reliability of a stock motor. Built right and matched with a good cam, it has all the ability of matching the power of a supercharger, and you should be able to build it for the same cost as piecing together a SC kit. This is the route I'm going to take once I eventually kill the stock 5.7 (I want to build a 392 based 6.1)
I've done quite a bit of research on this, and just take your time and figure out what you really want (and the headaches associate with each). I don't have to worry about trans reliability (well only the clutch) but that is one area you will have to figure out some info on. There is a few options for built 545 RFE's, but driver treatment is a big factor in these autos life. You also would need to have a tuner of some sort for a custom tune (being an 05 I would go SCT) for any of the above options.
