If you plan on going that route, there's two options that don't cost too much. I have a buddy with a '96 who did the 1.5 inch taller front springs with an add a leaf in the rear - it aligned well and gave him plenty of clearance for 33" tires without contact off road.
Check out the two links below. It's not much more to get the taller springs than it is to do the spacers. The taller springs would be a better way to go.
Any more than 2" of lift and you'll
need drop brackets for the radius arms, etc. That gets expensive. In both cases, like was stated by others, you'll need a rather pricey alignment. Both the links below include the adjustable alignment bushings you'll need to get the camber and castor back close to specs.

Plan on your alignment costing about $200 +. Anyone willing to do it for much less doesn't understand the TTB suspension enough to do it correctly! There's only one alignment shop in my whole area that will deal with the Ford TTB front suspension when it comes to changing camber and castor.
As far as shocks go, it's like arguing Coke vs. Pepsi. I know from personal experience that the Rancho RS 5000 is affordable and tough as nails. I can't speak much for others. If you plan on wheeling hard, they'll work great. If you're looking for a better ride, maybe go with a different brand.
Best of luck!
