Narrative:

Enroute received a cabin automatic inoperative message on upper EICAS. As automatic 1 was placarded; we were running in automatic 2 and switched to manual. Completed the QRH checklist through to the pattern altitude step. I decided to continue to filed destination; after speaking to maintenance control; as we were able to control the cabin pressure in manual. At a while later I declared an emergency with center as we were going to need a 500 FPM descent into our destination. While descending; received a spoilers advisory message on the upper EICAS. Completed the QRH checklist and landed uneventfully. I suggest we do not dispatch aircraft with inoperative subsystems.
