If you are getting Desert Wind Maneuvers from Ebon Pheonix, why not use Desert Wind Dodge over Dodge?
As a Martial Adept you will probably always have your Move Action anyways, so it would not be difficult to activate.
I've always liked taking multiple Marital Adept classes when going into Mot9.
Instead of going Assasin 3, maybe go Wizard 1 at first level and take Precocious Apprentice for the ability to cast 2nd Level Spells, then go Unarmed Swordsage 2 Later.
The 2nd Level spell you have access to will be quite potent for the first few levels, and once your Wizard spellcasting goes up, you will have access to a lot more spells known and the potent spells Wizard can offer. If you choose you can also take the Combat Wizard variant and get a free Fighter Bonus Feat over Scribe Scroll, as well as giving up your Familiar for the host of other Alternate Class Features.
Swordsage will give you more maneuvers and give you the option to apply some of the Maneuvers Known from Prestige classes to it as well as Warblade, giving you the ability to have the same maneuver prepared multiple times, and the Unarmed variant will get you Improved Unarmed Strike. The BAB will be lower by 1, but the free Weapon Focuses from Swordage will make up for the difference for the most part.
Just my 2cp.
