The nice thing about lifting a 2WD is that you can adjust the caster back to stock specs without screwing up the front axle pinion angle, thus (hopefully) avoiding death wobble.
Be sure to get an alignment after any lift. And don't forget that a lift will drag your front axle off center. You need an adjustable track bar, and the kits don't include that.
I think he means that you do not have a front axle pinion and do not have to worry about its angle.
Also, if you have access to a welder you can weld the old track bar bolt hole and redrill it to recenter the axle, there are many write-ups with pics on this job.
There's only two reasons to lift a 2WD truck IMO, looks and high speed off roading, the first can be as cheap as you want and the latter needs top quality components, careful what you buy, some "quality" lift kits will still ride harsh.
Like 87CherokeeChief said get the full packs you'll get a smoother ride and longer life, if money is tight well its your time and money so... try the dakota spring packs from the junkyard (search the forums for how), you can always buy new packs later.
The main problem with 4WD kits is the good ones correct your front driveline angle with longer control arms, this may be an unnecesary expense for you. That being said longer control arms have less angle, less angle equals smoother ride, level being ideal. Lowering the frame mount for the LCA will get the angle back to zero degrees but eats ground clearance which you probably wont need much of considering what you can do with a 2WD.
Sorry for the long read, my best advice read, read and read as many posts as you can, people tend to forget certain details that you need.
