Preferred caster is +3.5 degrees, the acceptable range is +2.75 to +4.25
Preferred camber is +1.5 degrees, the acceptable range is +1 to +2
Toe-in should be 1/16 to 1/4 inches (I tended to set them as close to 1/16in.)
..but caster is not the same as pinion angle...but definately dependent on each other on a solid axle

I've experimented with toe-out an' all and decided "I like" 0 to 1/32".
YMMV
You got a ~flat ~level place and a good 1" wide tape measure? ;)

What I found taking mine to the dealer twice, is they won't bend an I beam.
If it's "within spec" they won't adjust the toe-in either.
Charge you for the work, but not even touch the bolts on the clamp.
Mechanics get paid on speed, not quality of work.
When you pay someone to do manual labor for you...
you are paying them to go as fast as they can. :)
Leave me out of it.
Both times they left the toe-in closer to 1/8" and front tire cupping was the
result. That's when I decided I could friggin do a better job than the "pro". :/
The main reason I can get away with it is... I have the twin-I-bean
suspension and it lends itself to a-do-it-yourself-er since toe-in is all the
dealership will adjust or "will ever have to" adjust on these rugged, simple
suspension systems.
And figured out how to make a set-up where I could get repeatable results
when measuring. As simple as that.
BTW, the "flashy" raised letters on a tire will screw my method -right up-,
right now. ;) ...never had that trouble on anything this ditch-digger ever
bought tho. ;)
