Hi

I wish you the best with your Brandywine tomatoes but I don't think they will set and ripen with the temperatures dropping, it is better in the fall to plant short season varieties and leave the long season varieties for spring. Green beans the same.
Chinese cabbage, miners lettuce and broccoli will do fine even after the freeze, last winter I only cover the lettuce in the bed, all the other crops were uncovered and did fine. If you plant collards are very good after the frost, they get sweet.

Here is a picture of the lettuce that got covered
