I did mine at 23 and 24 weeks. The classes we wanted to do were having a break, so it was either that or around 35 weeks which was too late for me. For me, that was around the right time. I was in second trimester so still had heaps of energy and wasn't so big and awkward that it was uncomfortable and that I couldn't practice the positions and move around. I don't feel that I have forgotten anything - however I am starting again to slowly read over the materials presented to refresh things.
I'm not sure as to class timing. We only had the option of two Saturdays, 9 to 5 pm. They were LONG days. I know for us we couldn't have done the 6x2 hour options due to work. We would have missed classes and been late, so weekends were the only option for us.
As for breastfeeding, I did that last week (30 weeks) again due to timetabling rather than choice. Most people there were around the same time in their pregnancy. This one wasn't as long or as focused on moving around so I think you could do it later in your pregnancy.
