Welcome to the forum, Adam. I too have a '02 4.7 non-HO.
Lets lay down the basics before you start throwing money and parts at your truck:
What's your budget?
Do you plan on daily driving?
What octane gas do you want to run?
If I had access to your wallet, here's what I would do. I'd get a reman motor and before swapping it in, I'd throw in some HO cams (they are on national backorder but you can get a set used if you look hard enough), and some Beehive springs. the HO cams have a more aggressive profile, and make significantly more torque down low. the HOs are also cheaper than the other available grinds out there. They are arguably the best "bang for the buck" profile available to date.
I'd get the 2008+ 4.7 intake manifold, along with the necessary Throttle Body adapters from Nick at AirRam.com . To my knowledge I am the only person to successfully swap this manifold in a 4.7 WJ. I can personally guide you with the install.
Speaking of TB's, a easy way to gain some throttle response is a ported or bored TB. I sell ported TBs, but other vendors that cater to the 4.7 are the Fastman, and F&B sells Billet castings.
Regarding an intake, I'd honestly piece together one using some Aluminum piping. I had a 3" plastic intake and when I swapped to the '08 manifold, I opted for a 4" system I put together. The sound is unlike anything else!
With the above setup, you can run a stock tune, but you'll be at the point where you really should consider a custom tune. SCT is the only company that currently sells custom tuning programmers. I am currently running a stock tune but I have tuned in the past with Sean Powell....he is among the best. I am running the above mods (minus HO cams- I am still running non-HOs) and above 4500 rpms I see AFRs of 13.2-13.5:1. This is , IMO, right on the edge of being safe on a stock tune.
The above mods would cost you approximately 1500 (2000 at most) on top of the long block. You'd be good for roughly 350 crank, on pump gas, and with better than stock drivability. This is a setup your wife could drive ( although I doubt you'd want her to
) , all the while it'd rip from off-idle to 6000+ rpm.
