pretty much just went through bloguide & wiki and found where they drop&from who.

Quickstryke back: Prison Break (elite will drop Quickstryke elite)
Quickstryke chest/legs/back/waist is Prison Break, while head/shoulders/hands/feet is Phantom Zone

Military Tech will depend on your role: http://dcuobloguide.com/styles/military-tech/

Robotic legs... there is no such item. It's only head, shoulders, hands, and feet: http://dcuobloguide.com/styles/robotic/

Heartshard is role-dependent and only for healer or tank: http://dcuobloguide.com/styles/heartshard/

Snake is available for all via the DPS role, but has additional chances for healers: http://dcuobloguide.com/styles/snake/
