I'm afb at the moment, but I seem to recall being thoroughly underwhelmed by the tob legacy weapons with the exception of what might have been the diamond mind or iron heart versions, neither of which do you much good.
I'd pick up a collar of umbral metamorphosis, either temporary or not, since the dark template is right up your flavor (and I assume you'll be a sneaky mobile combatant).
Outside of that, with not much in the way of boots, there's a pair in the MIC that's around 2500 I think that allows five 20 ft teleports a day, or burn more charges for fewer but larger jumps. I recall it being a little more than twice as expensive than the anklet of translocation for twice the range and more than twice the uses. So that'd help with mobility.
And it's not as sneaky, but I like carrying the feather tokens for tree, anchor, anything suitably heavy. Instant walls, distractions, destruction when a massive tree appears out of nowhere, or just dropping one on your opponent make these cheap, tiny tokens well worth the piddly few-hundred gold they cost.
