Yes, the importers are bugfixed and updated at the same time we put out a new version 7 update. So with RC1, both of these will be fixed.
As for the width of the topic, there is one post where it has a long string of words with no spaces. In a browser that supports it, such as Firefox, you'll get a horizontal scroll bar in the post itself so it doesn't stretch the whole layout. IE6 doesn't support this, though I think IE7 does.
