It's well...it depends on your maneuver selection. I think White Raven is perfect for a leader rather than a frontliner too. Try this:
Stances:
Bolstering Voice
Tactics of the Wolf
Swarm Tactics
Maneuvers:
Leading the Attack
Douse the Flames
Tactical Strike
White Raven Tactics*
Covering Strike
Flanking Target
Order Forged From Chaos*
Clarion Call
Swarming Attack
War Master's Charge
The *s don't require attacks at all, and the rest boost others' stuff with your attacks, aside from War Master's Charge which...well, yeah. But it's a level 9 maneuver so I'm just giving it a free pass.
As for the Bard song, well, meh. I'd still think it's worth it; maybe talk for stacking the Warblade/Crusader levels with Bard for duration of Inspire Courage too due to the way it got rewritten with Song of the White Raven?
