I think you're getting the way things would work wrong.
It would be something like:
Tactical warlord: Move up to enemy, warlord's favor benefiting the inspiring warlord. Guileful switch with inspiring warlord.
Inspiring warlord: Move to flank enemy: inspired belligerence, war of attrition. Action point (use bravura presence): hammer and anvil. 1W+mods+1/2 lvl+Resc lord Int+Taclord Int and taclord attacks at +Insp lord Cha to hit and +Insp lord Cha damage. Bravura presence bonus basic attack. 1W+mods.
Barbarian: Charge. Hit for normal damage +2x Cha. Action point (take advantage of bravura presence) Attack with howling strike. Hit for normal damage+2x insp lord cha +Taclord Int +1/2 lvl +resc lord int. Make a basic attack and hit for normal damage+2x insp lord cha. Drop enemy (I mean, come on, he's taken 10W+10x mods+2d6+8x Insp lord cha +2x taclord Int+2x resc lord int+ level damage; that's gonna leave a mark). Swift charge howling strike and hit for normal damage+ insp lord cha.
Resourceful warlord: Move. Commander's strike on barbarian (hits for damage+2x Insp lord cha +Resc lord Int). Action point (use bravura presence) Staggering spin. Hit multiple opponents and push one into the taclord and insp lord and another into the barbarian. All three make basic attacks and the taclord and barbarian add the insp lord Cha to attack and damage. Guileful switch with taclord.
Taclord. Move away from foe and commander's strike the barbarian who attacks at +Insp lord Cha for basic attack +Insp lord cha +taclord Int. Action point (use bravura presence) and attack with surprise attack. Hit for 1W+normal mods+1/2 lvl +resc lord Int). Give an attack with combat advantage and +Taclord Int to hit to the barbarian who hits on anything but a 1 for W+mods+Insp lord Cha. Take bravura presence attack for 1W+mods+Insp lord Cha. At this point, I'll assume we need to move on to another target. Guileful switch with barbarian.
Barbarian. Howling strike, charge someone else (maybe the guy the taclord peeled off from). Smack for howling strike+Insp lord cha mod.
Bravura warlord. Move up to foe who is now next to the Insp lord and barbarian. Action point hammer and anvil. Hit for 1W+1/2 lvl+taclord Int+Resc lord int, barbarian makes an attack for 1W+insp lord cha +bravura lord cha. Standard action: Provoke overextension. (On a hit, the enemy attacks him--barbarian uses Battle awareness to make an attack for 1W+insp lord cha. If the target misses, the barbarian makes another attack for 1W+Insp lord cha +bravura warlord cha). We're probably done with this third foe now. Guileful switch with barbarian.
Barbarian. Charge, howling strike something else for 1W+1d6+Insp lord Cha mod.
Resourceful warlord. Move to barbarian's position. Minor action: Adaptive stratagem. Commander's strike and barbarian attacks for 1W+Insp lord Cha +2x Resc lord int.
Inspiring warlord's turn. We've made it to the second round. If there's anything still alive on the other side, she might bust out warlord's strike to give her allies 1+her cha to damage until the end of her next turn. But that's a power bonus so she will probably move to the enemy, rousing assault, and guileful switch with the barbarian again to get him into position for everyone else to commander's strike him and take maximum advantage of that adaptive stratagem.
