In your area I would expect a decent fall crop from goldenrod, aster and bamboo. We super up to give the bees room to work. Remeber they are drying nectar down a lot to make honey, it isn't just a matter of collect nectar and fill honeycomb, there is a lot of work they do to dry it and repack it often. Only giving them one super at a time during a heavy flow can really choke them off for space. And you don't want them storing honey in the broodnest because they lack room above. On my strongest colonies in good locations, in a good year I can get 180 lbs from a colony. At 40-45 lbs in a medium depth super thats 5 almost full boxes.
If your packages have italian queens be aware they don't tend to winter well up here. They aren't thrifty with honey stores and will often starve out by spring. It's late for me to advise requeening (although it's what I would do), so after the fall flow feed the dickens out of them. Just be careful they don't totally pack the brood chamber. They need those new bees going into winter. My preference is for carniolin or buckfast queens. Never tried russians but many like them. Carni's aren't as gentle as italians but they are a great bee for the north. Buckfast are gentle (usually) and they winter well. Both can be quite productive given proper care.
Second on following Mike Palmer's advice, he's a very innovative and experienced beekeeper. Don't always follow his advice, but I always listen and consider it.
