Acklay strategy is similar to Wat strategy in that Ability Block on the AOE is how you survive, but for Wat spreading AB far and wide is most important. For Acklay, if AB doesn't stick on the AOE Jedi you have to keep hitting them until either it does stick or they are gone.
As far as not hitting the Acklay, I can't say that is something I would do because Acklay gains offense with every defeated Jedi, and if you aren't hitting Acklay then you are targeting Jedi and they go pretty quickly. Only hit the AOE Jedi and leave them alone if AB sticks on them so you can ham on Acklay. This is what has worked for me the last two times.
G12 health pieces are most important to get through the Acklay gear check AOE: medpacs are a must because they are easier, furnaces recommended to reduce vulnerability but not vital.
The most important details were g12 medpacs, fast GBA, and high CC Soldier. Call Soldier for assists, don't taunt with Sun Fac, hold Poggle debuff move to clear Daze.
There has to be a better way to use SF Blind though.
