I'm going through the thread right now to see what was discussed previously, but from the memory we can build:
1) Special tech station for tending to Devices - prerequisite to tinkering with Devices at all
2) Start on the Power Plant (9 slots) - will help with powering IAE on the next Template Install, giving us a non-combat slot rather than using us as power source
3) Finish the Dragon Drone
4) See about upgrading the mobile command center
5) Possibly build that specialized fabricator for medical supplements
EDIT: Here's that was there the last time.
