X2. Doing it yourself you'll learn a lot about how the front end works. If you have your stock control arms then you won't be able to adjust your caster anyway.
I do mine as shawn said with a tape measure, its about a 30 minute process tops. You probably want about 1/8" tow in, or in other words so the front of your tires are pointed together. You can get this measurement by just running the tape measure from both sides front and rear and taking the difference as your tow in/tow out. Then adjust it by turning the shank on the drag link (runs from the passenger side knuckle to the pitman arm)
Take a test drive after you rough it out. If you're around Raleigh I'd be happy to do it for you at my house, but IDK anyone in your area.
