The alignment will depend on what kind of driving you want to do. Installing the bushes will provide a more stable platform for the car so the alignment can be set to close tolerances. As the car changes and you add bits, change height, go from autocross to drag strip etc., the cars alignment can be changed to reflect how you want the car to handle. Different applications (track, strip, daily driver)will use different alignments.
Once you have a plan for the car, get the new parts accordingly. Work with the vendor on the set up on the car and the alignment. They should be able to provide alignment specs to dial in the car according to the installed upgrades.
