Rebuttal limited to one page
You don't need to say much about simple things like typos. As for the other, if you go over the one page limit make sure than everything essential is on the first page. Even that is a bit risky if someone is a page limit fanatic. The best route is to say what you can in one page, mentioning only important things. 

But if you think of it as a "response" rather than a "rebuttal" you won't get into an argumentative mode which won't serve you well.
