Hi Leslie - according to the news you guys might need a program on good soil drainage!
I haven't seen any programs in person but I will say from the ones I've seen on Facebook, one thing that I find really interesting is seeing photos of the parents along with the various offspring. Karol Emmerich is very good in this regard.
In terms of a 'back to basics' I think it would be good to tackle some of the more frequent questions. That is to say, what to plants look like in the spring vs the fall. Rust...how to deal with it once it inevitably arrives. Proper feeding for plants in the ground vs in pots ( including soil, soil amending, and soil-less mixes). Perhaps the basics of dividing a clump.
