I wouldn't wait so long on getting Thicket of Blades up, I'd pick it up as the 6th level feat, so you can get that part of the combo up early on. Alternatively, the Devoted Spirit maneuver item equivalent to a Crown of the White Raven can save you a feat. Better than dipping Crusader and having to deal with two ILs, since your Warblade levels would only count for half of Crusader and you couldn't pick it up that way till 9th, as a Warblade 8/Crusader 1.
