Flashpoint and its install (Please read)

[FDesign]

So, Ive got Flashpoint, Red Hammer and Resistance. Now, what I want to know, is that which official updates do I need to add to have everything officially released in it. If I install Flashpoint, then Red Hammer and then Resistance, then do I have all the stuff that every update has before the Resistance was released (aka all the updates from 1-4)?
