I did mine alone.
Let the alignment shop jack with the cams for $90-$100 when they align it. I never did get my old truck aligned...didn't even center the steering wheel. Should have? Yes. I just never got it done. It never drove different or wore the front tires any different in over 80,000 miles with the leveling kit. I haven't gotten my current truck aligned yet. No way I get that lucky twice.
I put in a Ready Lift track bar bracket, so I can't help,with removing & installing the other end of the bar. Adjusting is as simple as loosening the proper bolts adjusting, measuring, adjusting, repeat. Just like centering the steering wheel.
Brake line replacement isn't bad either...until you have to bleed. Then it's a pain, but there are kits that make this stupid easy. If you are getting the 2.5" kit, it may come with brake line relocation tabs. No bleeding necessary. Disregard. I see that kit comes with new lines. Still no worries. I did my 2005 brake lines myself. Wasn't bad. I haven't replaced my 2015 brake lines...I'm being lazy and cheap.
