I finally ordered Gardening Month by Month in the Carolinas and I'm having fun thumbing through it. I was happy to read that now is the time to get lazy with your roses. The fall is the time to stop fertilizing and also stop pruning off the dead flowers (aka rose hips). I was surprised by this second point, but my hands have been too full to carry around the prunners lately anyway. Apparently if you pluck off the petals and leave the rose hips, the plant realizes it's time to stop making new flowers and get ready for winter.
