For strongholds, my bar is
Light Strike, Pummel, Flurry, Concussive Blow II, Featherfoot II, Jarring Strike II, Simian Thrash, Haymaker II, Seismic Shock II, Second Wind II
I don't remember the order of my other bar. It's basically Rampart II, Sentinel, Ferocity II, Raging Strike II, Invigorate, Bloodbath and Victimize II. I know Blindside II and Keen Flurry are in there somewhere.
And then my 3rd bar has Defender, Sacrifice III, Resurrect and Siphon MP II. I realize that doesn't cap me out action wise but I can't think of it off the top of my head at the moment >_<

Basically, the top bar is what I use most frequently so I want quick access to all those skills. I have Second Wind II up there so if something goes wrong and I take unexpected damage I can just hit 0 for a quick restore.
Rampart II is for "ohshi-" moments and I essentially pop Sentinel the minute I pull hate to reduce damage right off the bat. The rest of that section is fairly obvious imo.
Defender is there to play it safe when the situation calls for it. I have Transcendence so I always have Resurrect set with it along with Sacrifice III to cure myself or toss it to someone else and Siphon just helps keep it up since I don't passive that often in there.

Swapped around a bit for Ifrit since you don't really get any opportunities to use the counter skills on him. Seismic Shock II is replaced with Follow-Through and I know I have Emulate somewhere in there. I have Quelling Strike II to stack on Victimize II too. I'll repost with exact bar setups when I log on.
