Hi Cindy -- how weird that we are both supposedly in zone 5 when you are at the bottom of L. Mich. and I am at the very top!! well, whatever...
All of the things you mentioned planting are pretty cold hardy and I don't think you'll have any problems even if the weather does get unexpectedly cold. Just covering with a sheet or some "floating row cover" would likely be plenty of protection. (I have a Chinese cabbage sprouting back up that overwintered in the garden...)
I hope you have a great gardening year!
