Do I need intake/headers to use FI?
I want to do either a supercharger or procharger setup and I'm wondering if I need to do an intake exhaust mod also? Can I still use the stock hood on a supercharger?

This totally depends on the forced induction you choose.
If you choose a Vortech/Procharger system (basically the same thing from 2 different companies), no hood modifications are necessary. This is what I put on my 2006. Here it is:
If you go with a Maggie (which sits on top of the engine), then you'll need a new hood to clear the supercharger box.
A new air intake system comes with most systems, but you don't need to install new headers unless you want to. I chose not to because my car is more of a GT car - I didn't want the loud noise coming from headers or the smell when having to remove the cats from the exhaust.

I am using the PS1 ProCharger and I'm also running DynaTech's 1 7/8" headers w/cats, x-pipe and Corsa exhaust. When headers and an efficient exhaust system is used, you can run a smaller supercharger pulley and make more power. A stock ProCharger on an LS2, w/o headers will make approx 5.5 to 6psi of boost. Same pulley with headers will probably lose 1.5 to 2 psi because the engine is more efficient. So, you can install a smaller pulley, up the boost to where ProCharger intended it to be, and produce even more power.
but is ready for some serious azz whooping if I need

We do a lot of Prochargers with headers, and high flow cats, and are always happy with the results. 500-550 RWHP is the norm with just the supercharger and header setup.
If you're looking for stealth, the Procharger is a good way to go. The Magnuson is also a very good choice for stop light to stoplight action, but that raised hood is a dead give-away that something has been done to the car!
Feel free to let me know if I can answer any questions,

Then you'll want to leave the headers off the car. My fi 2006 averaged about 32-33 mpg on a 2800 trip in September. It did quite well. The only real noise was a slight s/c whine, which I find quite pleasing. I didn't go for a total brute setup - no new cam, no headers, no messing with engine internals. If you want a livable C6, this is the way to go IMO.
