If flexible retraining is allowed I would try this:
1: Weapon Finesse (but retrain it as soon as you can afford a (Alchemical Silver? because you'll be going from 1d3 to 1d2 damage) Feycraft Quickrazor), Darkstalker, FOI, FOI
3: EWP(Quickrazor)
6: That poison thingy? (Master of Poisons.)
I guess if you put more weight on Warblade you could go Str based and use some heavier armour eventually, in which case you either really stack up on the FOI, or take something else handy at level 1. Like... I don't know. Weapon Focus(katana) if you want to go Iaijutsu-master eventually. Nymph's kiss if you want to REALLY stack up on those skill points. Able learner is also always a candidate, because multiclassing means losing all those neat class skills, otherwise.
The neat thing on a Quickrazor is that you can just use a spear at level 1, but keep the spear until later, even when you have a Quickrazor, so that you can threaten with reach, but attack with the Quickrazor when you want to use Iaijutsu-focus. You can do this because a Qickrazor doesn't need a hand until you actually use it, and taking a hand off a weapon or putting it back is a free action on your turn.
