The order isn't "etched in stone" but there are a few things to consider:

First off, when you install the lowering springs you are changing various suspension angles on the car. To do the job right, you need to do the alignment (Camber correction), Adjustable LCAs, and the adjustable panhard bar at the same time as the springs.

The other parts can be installed whenever you feel like it, in no particular order. However, it will be cheaper for you do do it all at once. That way you don't have to pay for the mechanic to take apart things that he already put together once before.

I suggested the LCAs first becasue they address a major factory weakness, and they are needed before doing the springs.
