I'm not that good with factorums, so I'll probably miss some good synergy. Still, with 16 other levels under your belt, your first warblade level at 17th level will give you an Initatior Level of 9, giving you access to 5th level maneuvers.
I know factorums are supposed to be good at getting skill checks really high. There's a 6th level Diamond Mind maneuver, Greater Insightful Strike, that lets you deal damage equal to double your Concentration check. Similarly, there are three maneuvers that allow you to make a saving throw using a Concntration check in place of the save.
Iron Heart Surge seems like a good candidate in that you can get rid of any number of negative status conditions.
White Raven Tactics will let one of your allies act right behind you, giving them more actions in one round.
If you need, there is always the Mountain Hammer line for getting past damage reduction and hardness, but I don't usually put much focus into Stone Dragon, so the prereqs might seem a bit steep.
