Shadow Hand has great stances at all levels, but IMO its maneuvers don't get good until later on, especially the strikes. At your level, you can get up to 3rd level SH maneuvers...
Shadow Garrote is a solid ranged attack option to add if you lack spells for the purpose. Cloak of Deception is a nice buff, but mostly if you have sneak attack. Shadow Jaunt series is still potentially useful since RAW it is *not* supernatural and thus you can even use it in an anti-magic field. But a) most DMs house rule it to be Su and b) the times where that's useful are so rare, it's not worth keeping readied. So yeah, skip it.
I really can't recommend any of the other low level SH maneuvers; Child of Shadow and Assassin's Stance are great stances, though. Island of Blades also would be if you had some source of sneak attack other than Assassin's Stance.
(Much) Later on, One With Shadow, Enervating Strike, and 5-Shadow-Long-naming-ton are all good. If you can get a high DC, Hand of Death and Death in the Dark are also good. A lot of the others... I don't care for. Especially avoid Ghost Blade, it is mind-bogglingly weak/useless for its level.
