I did exactly what you are about to do with the intent of going to an alignment shop but I never went to an alignment shop. Bec after I installed the camber kit in the front (skunk2 adj. upper arms) the alignment was so bad I couldnt make full turns, I bought some string, a plum bob and an angle level with the idea that I would temporarily align it but I had to get into it so much that I was figuring things out on my own, and although it took me many hours the car drives straight as an arrow and I dont think Ill ever have to pay anyone to align my car ever again.
