AFE intake, Magnaflow Exhaust, and see what that does for you. If it isn't enough go with a tuner of choice. An engine is an air pump so the more you get in and out the better it will run.
And if that still doesn't get you up the hilss like you want to go then add a procharger! :D
Don't waste your money on an intake or exhaust. All that will change is it will be noisier. Your engine has electronic controls that only allow it to use as much air as it needs. Making more available won't change anything. The companies that sell this junk always start their claims with "adds as much as". If it was this easy to make more power the factory Engineers who designed these engines would use it.

While what you wrote is your opinion it is completely wrong. The electonic controls you speak of can and do get altered with a programmer. The reason manufacturers don't use higher grade intakes and exhaust is usually a cost vs. return for a whole line of products. I can guarantee an improvement in both HP and TQ as I have dyno'd my truck with the simple additions listed and now have 65 more HP and 100 Ft/lb. on the ground than the orginal setup made at the crank.
As the truck is a 2003 I did not consider it as having and warranty left. The thought of gears did come to mind but as the OP pointed out it is a 4x4 which can be very expensive not to mention the DD mileage would drop.
With the mileage that is on the truck I too agree that it should be able to pull much better than it is. Maybe a trip to a qualified mechanic to make sure everything is working properly would make more sense.
