Looks good but I might try Veteran Instincts. To take any advantage of ATC, you will need a target lock. High PS makes it a lot easier to get a target lock on a ship that will actually stay in your arc.
I dont know where i sit on VI for Maarek yes it means the first round of combat your always going to have a target lock but I'm thinking there is more then just one round of combat. I think i would rather have something that gives me stronger attacks all game then making sure my first attack will have a crit that would most likley hit shields. but Vi does give him a chance to ark doge
I am feeling Predator or Lone Wolf for him more than VI I think personally, as I would want a ship shooting before him personally (and more offense means more crits actually stick)
The really hard choice for me is Vader, I love Outmaneuver+EU on him now (I've given him Homing Missiles too and that was really fun) Do I keep using outmaneuver or switch to predator for the rerolls since you can't use the TL now.
