I'm sure it wouldn't hurt to.
Quote: "I also looked into Morph targets in Anim8or, but that left me more confused."
Indeed, but the downside with Anim8or is that it doesn't export animations (or at least at version 0.9 it couldn't)
Quote: "And have u tried WaveFront Obj?"
I don't think that carries animation data, it keeps polygon and material data. But it's worth trying every possibility.
I can only see animating them yourself as being the only solution, but I'm sure that's not good for your workflow, but use a generic bone structure and animate it, then apply different models in Truespace. (Although I found TS 5.2's rigging/animation tools very buggy on my system, so I don't know how TS4 is with your system.)
