How to link one particular post to comments

Hi Guys I hope you are having a wonderful weekend!

I have 2 questions I'd like some help with.

a) I am using "Ultimate Facebook", but I would like to add also "Comments +" plugin, how will they both work together? I mean if someone connects with facebook using Comments Plugin, will the comment appear inside the "Ultimate Facebook" comments feature? A bit confusing right?

b)Let's say I create a Post inside Facebook and I Boost that post using ads so people are commenting directly in that post, is there a way that I can link those particular comments to a Post in wordpress? The reason I don't want to create a post in wordpress and let Ultimate facebook autopost it and then boost that post is that if I do it inside facebook I can create a better looking post.

Thanks for your time!
