Well, you must install the games in this order
1) SF2
2) SF2 Vietnam
3) SF2 Europe
4) SF2 Israel
6) Expantion pack 1
7) Expantion pack 2
8) SF2 North Atlantic
And then DLC's
Ok , about the updates, If you have bought them during different times each installation will have a different version, some of them may me compatible while merging them, others not, I believe that you can redownload purchased games or DLC whenever you want , so if would redonwload every game , and the installations you'll get will have july 2013 version, and then , you won't have any problem merging the games and other features.
