We've hardly been doing 'not much of anything', Harry. Research into our current situation and its ramifications for us now that we're here is a fairly important step. Especially, since, as you point out, we don't know if the hex or hexes are still in affect. I found the Matrons' log journals in the Hospital Wing yesterday. It looks like they had to bring Pomfrey out of retirement when the younger witch who'd taken over was one of the first victims. But, there are symptoms and theories here that may be of use to answering that question.
However, you do make a good point that we need to investigate the status of the rest of the wizarding world and gather what supplies we can while we have access to them.
As for the Full, the only thing you lot need to keep in mind is to stay inside the castle that night and not act like the Gryffindors so many of us are. I'll head out for the Pitch well before sundown, which should help with keeping me away from both the castle and the forest during the night. James and Sirius know how to handle the morning after and can come get me if necessary.
