If you take the one level at high HD, you can actually get really good manuvers. Because non-Initiator levels count as 1/2 initiator levels, ToB is probably the dip friendliest book. At 14 HD, I believe you could get 4th level maneuvers! (maybe 3rd...)
If you've got suggestions for what would be best to take for a ranged user, I'll listen.
You should take two levels of swordsage for a mid level stance, an additional +1 to BAB, reflex and will as well as an ac ability that you can use if you ever loose your buckler.
A good setup would be as follows.
Stances: Stance of Clarity, Hearing the Air
Manuevers,
Cloak of Deception, Shadow Garret, Shadow Stride, Moment of Perfect Mind, Wind Stride, Zephyr Dance, Fire Snake
This set up gives you a nice set of options. All of which are usable as a ranged character and often enhance that role. Some are not so good and serve as requirement fillers but you just have to not ready those, namely wind stride. A good set of readied maneuvers would be cloak of deception, shadow stride, Fire Snake, Zephyr Dance. Unless you have a good number of ranks in concentration in which case replace zephyr dance with moment of perfect mind.
