well, that's the hard part. everyone -thinks- they know what they want and what they'd be happy with....until they install it an catch the bug. "well i think i want to add this now, and that, and add this".
however, i would recommend that if you're only looking for a little bit of lift, you're not going to be doing anything else (bigger tires, etc), and you're pretty happy with the stock ride, then just do the deluxe suspension lift from 4x4parts.

it's cheap, kind of easy to do and will make your ride slightly more firm. the package is complete. however you may need to buy rear camber bolts. look under your truck from the rear and to the inside of your spring. if you have these, then you already have rear camber bolts and you do not need to buy them. it will be a bolt with a disc under it with those notches.
and after you get the new suspension parts installed, then you'll need to have it aligned. and keep in mind that you'll probably have to align it 2-3 times as your new suspension parts settle. i had to get mine done 3 times within a weeks span, but it's been just fine after that.
