There is one more set that also changes. The armor from Imperial First Mobile Fleet/Republic Hyperspace Armada changes colors when you sent it over to another faction.
Republic is blue with orange: http://tor-fashion.com/hyperspace-hotshot-pub/
Imperial is gray/brown with red: http://tor-fashion.com/hyperspace-hotshot-imp/
According to the description Force in Balance should heal you of 20% of your damage dealt. 10% (normal FiB) + 10% (100% of 10% thanks to Focused Insight) = 20 %. So if you're only getting 10% than that is a bug, but you should not get 100%.
3.0 is something different then Shadow of Revan. Everyone gets update 3.0. And the ones with early access get the expansion Shadow of Revan at the same time. Just like with 2.0 and Rise of the Hutt Cartel.
