The TD-17A set includes all slots- Head, Chest, Belt, Bracers, Leggings, Boots, and Gloves. The chest is from the Gree quests on Coruscant. Everything else but the Bracers and Belt comes from the Taris Bonus series, and the heroics in that if I'm recalling it correctly. You can't really quote me on that, but I'm pretty sure that's where they came from. To note for anyone planning on going back and redoing those Heroics and expecting to get the entire set: The Legs come from the bonus series itself- if you have already done that and discarded them, you won't be able to get them again.
