Do you want to do it all in one shot? or over a period of time piece by piece. What kind of budget do you have? or money is no option? Who is doing the work, shop or yourself? What kind of millage does your engine have? What gears do you have now?

Well...need some info first. You have a 4.7, I'm going to assume automatic. Do you have 20" rims? If they are factory install then you should have 3.92 gears. If they weren't installed at the factory then you may not. Look inside your glovebox, there should be a sticker (if it's still there) that lists some of your options. Is it a reg cab or quad cab? 2wd or 4wd? How much mechanical ability/aptitude/experience do you have?

Just a preliminary list, depending on what you are capable of doing or can afford:
1. Superchips 3865 programmer. I normally would say a 3815, but I heard an
unsubstantiated rumor that SC might have extended their trans tuning to
03 4.7's only.
2. CAI (air intake). Your choice of what looks good to you, there are many
out there.
3. Exhaust. If at all possible, try to at least replace the Y pipe and cat
back. The whole thing would be great, but gets pricier.
4. Gears. Biggest bang, however pricey even for 2wd and if you have 4wd
you have to do both ends. ALSO keep in mind moving up to say 4.56's
your highway mileage is going to go south quickly.
5. Higher stall aftermarket torque converter. Also changes the nature of the
vehicle, but harder to do because you have to drop the trans. I have
done this more than few times, dunno if you have ever done it. Should
you decide to get one, best idea is to contact the TC manufacturer, tell
them your combo/further intended mods and intended use for the vehicle
and they will recommend one.
6. Scour classified ads and ebay for 'HO cams'. These were the cams (4.7's
have 2) that were installed on the 260hp Grand Cherokee HO version.
They are VERY hard to find but are the best all around cams for a good
torque curve in these heavy trucks. There are other options, but they
usually require custom tuning to run right. 2008+ cams might be a viable
alternative, as are the 08+ cylinder heads. I know someone on another
forum was doing some test fitting of both to check PTV clearance.
7. I'm old, so bear with me on this one, for some reason it annoys me; NOS
is actually a company called Nitrous Oxide
S
ystems. Nitrous kits are available from a bunch of different
vendors; make sure your truck is mechanically sound before you go that
route and blow it up.

Take a peek at airram.com. They specialize in 4.7's. Keep in mind going faster in a 4.7 is a little more challenge than doing the same things in a hemi. There is alot of info out there to help you. Like I said earlier, make sure it is mechanically sound before you dive into all this. 4.7's are known for overheating issues, making sure your cooling system is good and up to snuff (rad, water pump, hoses, t-stat, etc) is paramount. You overheat it, you warp a head(s) and then drop a valve seat on to the piston. Not fun.
