[Is repairing a damage card considered a white action?]

Here's the situation.  My opponent bumped into one of my ships with a VT-49 Decimator with the Dauntless upgrade, which enables them to take a "white action" when they bump, treating it as a red action.  The Dauntless has the Blinded Pilot crit, which would make attacking in the next round bad but can be repaired using an action.  Can my opponent use the Dauntless' ability to repair the crit, or are those special actions (repairing crits, using Lando's crew card, etc.) considered different from white, red, and purple actions? 

[Grappling Struts and Barrel Roll]

Can Hyenas and Vulture Droids barrel roll OFF of an obstacle and still keep their struts open? Furthermore, would they simply rotate in space until they executed a 2 straight maneuver?

[Munitions Failsafe and Suppressive Gunner]

Suppressive Gunner states you can spend an "eye" result to force the defender to gain a deplete token or take 1 damage (defender's choice).  

Munitions Failsafe says after rolling attack dice for a torpedo or missile attack, I can cancel all dice results to regain one weapon charge.  

My question is, after rolling the attack dice, can I spend an "eye" result for Suppressive Gunner and then use Munitions Failsafe?
