Alignment advice/specs

My car has manual discs (wildwood) and 73+ hardware. 4spd manual steering- The wheel/tire setup looks like **** in my opinion.
In addition, the steering box was shot...so that was replaced by a FirmFeel box...and planning to change the wheel/tire combo, but here's my question:

Do I get the alignment with the current set up...or wait until I change the set up?

Lastly, do I need specs to give to alignment shop?
Current set up:
fronts 15x7 215 70 15
rears 15x8 245 60 15

Potential New set up:
fronts 15x6 steelies 3.0BS (wheel vintiques) 215 65 15 or 205 70 15
rears 15x8 steelies 4.5BS 275 60 15
