Give it some time to re-sync everything. Your contacts, for example, should show up once it syncs with Google. The Facebook pictures will gradually make their way back as well (assuming they were Google contacts to begin with). The battery meter has probably been reset so, after running it down and charging it back up, it should get a feel for the limits and sort itself out. Keep in mind that it's going through a lot of processing and re-syncing to get itself to full status. That drains the battery. In other words, be patient and see if it sorts itself out over the next day or two.
