Facebook, late last week, updated the style of the Like button. My guess is that it was temporarily broken. This happens every once in a while where they make a change and bad things happen for a short period. It's usually fixed quickly, and that seems to be the case here. If you run into the same problem, let me know.
As for the comment box, I just looked around your site, but couldn't find an instance of the Comment box to see what you're talking about. You can change the width of the comment box in the Content plugin or Module parameters, if the width is cut off. If it's vertically cut off, I'll need to see what's happening to figure out a fix. Please let me know how you're inserting the Comment box (module, plugin, or {JFBCComment} tag)
I'm not sure what you mean by "what i need to do to see it leaving the postion of the button as it is now?" What are you trying to leave in it's position? If it's already there, why do you have to move it?
I answered the Share question in the other thread. Please keep your questions separate so that it's easier to answer specific topics in each post.
Thanks!
