How to set caster?
I would get the Camber & Toe sorted first.
The only thing I do with toe (if the entire front end has been apart) is simply rough it in so the wheels are halfway straight and the wheel is "near" centered.
1 Ride height, jump the car up/ down to "settle" suspension and take your time until satisfied
2 Set caster/ camber together
3 Set toe last.
You can MAKE the tools you need to align a front end, Google around, or you can buy a caster / camber ga. several places.
I got lucky. Some time ago, I found an old Ammco caster/ camber ga, some swivel plates, and a toe jig used for not much money
