Couple of Questions on WP and Satellites

[Enigma]

Ok do these facilities and satellites group together to for a group of components?

Does it make sense to create some WP with shields and armor to provide protection for the other platforms on a planet?

Does a single satellite or platform with Religious Talisman provide the special targetting capability to the other satellites or WP on the planet or in the stack.

Does the order of the WP and satellites in the stack or on a planet impact which ones are damaged or destroyed first. For example would a couple of WP with shields and Armor provide protection for other WP further in the stack on a planet?

Any help would be appreciated
