need front end alignment help

[69chevy lwb]

i have a few questions about the numbers i should be looking for when aligning the front of my truck to start the truck had awful understeer and bad straight line stability with stock suspension so with the addition of some air bags and lower strong arms i noticed a large difference but was looking for more so i added strong arms uppers, cpp 2 inch drop spindles, wilwood brakes, and kyb shocks after all this im not to sure how far my alignment will be i am still running my stock shim stacks. im looking for a fairly sporty feel or as close as i can get on a long wheel base pick up with manual steering my main questions are, can i set my alignment without tires and turn plates if i block the suspension and set my ride height? and what numbers do i need to look for should i set the passenger side to follow the crown of the road or match it side to side? thanks for any help
