Comments not showing up

OK, here we go...

1) I installed the ultimate facebook plugin. Everything went smoothly. I read the usage instructions, extended permissions and all...The "published to facebook" column in the "posts page" in the backend, displays "no". my question is how do i get it to yes? once its linked, i suppose the comments importer will work?

2) The comments/comment box don't appear. I tried unchecking the comment checkbox in "discussions. in the post. checking one and not the other. everything. No way to get it to show. I even checked that the single.php had the comments line. no dice.
