Hello Linda,
Thanks for getting in touch. Let me try to help you with that.
Basically both of them should be possible with some customization.
For the second one I would definitely recommend a template override for the single events template. You can find more info about template overrides in our Themer’s Guide.
The first one, showing all dates, is also possible with some custom coding, possibly with a template override as well. I believe this function would help you with that: tribe_get_recurrence_start_dates()
Let me know if this helps you get started on it.
Cheers,
Andras
