The Facebook app should sync comments on Facebook with those on the blog. So, you could just reply on Facebook, which would then automatically get posted to the blog. As for the other way around, when a reply is posted on the blog to a comment that was imported from Facebook, I think the FB app could handle that too, and post a reply to the Facebook thread: "Joe Foobar posted a reply to you here: [link to comment on blog]"
