Hello Donald,
Thanks for using our plugins and welcome to the forums! Great questions you have there, let me try to answer them for you.
Is there a feature pending or that can be developed to import RSS feeds from other sources into Events Calendar Pro?
At the moment this feature is not in development. We are checking how much need there is for this feature and if it gets enough votes then it will likely be developed. You can cast your vote here:

Can Events also inputted into the plugin be reverse updated to FB events or can it be developed?
It can certainly be developed somehow, however at the moment this is also not yet being developed. You can cast your vote for this one here:

I hope this answers your questions. Let me know if there’s anything else I can help you with.
Cheers,
Andras
