You can plant whatever you would like, that's the fun of it. Experiement with it, but I would suggest always using utilization cages so you know what they are eating. Many people plant alot of different things for a reason, that is what their deer eat. You don't even have to plant the entire plot with one mix. Keeping records is a good idea for you as well; what you planted, where, and when. My deer did not ear radishes or turnips the first two years that I planted them. Now they know what they are and will dig them out of the ground.
As far as timing, radishes and turnips, they should be planted earlier than most of the other stuff. For your region, maybe 2nd to 3rd week of Aug. You can then top sow the rest before a rain around labor day. Clover, wheat, oats, and cereal rye will germinate fine if sown right before a good rain.
I wouldnt start the dirt work yet. Even though everything looks dead or dying, it will still wrap up in a disc or keep it from penetrating the soil. I have done that many, many times and would highly recommend waiting. When the plant matter turns to dust when you step on it, then you are ready.
Not living in your area, this is my best guess for timing. Keep records, and let us know how it goes.
