check out the scotts front end as well. it is a one piece affair as far as the upper and lower control arm mounts so less chance of making a blunder on getting the wrong angle etc when you weld them in. all that engineering is done when you get the crossmember. the upper control arms are also adjustable. some bolt in as well so you don't need a welder.
read the understanding independent front suspension in the heidts site before you decide. some good info there on geometry, bump steer, antidive angles etc.
if you don't mind the solid axle and want to keep the rest stock as far as springs etc, then how about a front disc kit for the original axle, a hydroboost for the power brakes that will fit under the floor with a new dual system master cylinder and proportioning valve and a power steering kit that will fit in place of the original.
open wallet here.not gonna be cheap but would make the truck much more enjoyable to drive. sit down and do a feasability study with budget and then add some for good measure. before you start make sure the frame is straight and true with no issues.
