Answer

The phrase carries some feeling with it, like joy, surprise, or disappointment.  It looks odd in the first sentence because it seems like a neutral, factual report.  However, it looks good in your second example.

Answer

In the US, we usually say, "to top it off", not "all"

As Michael points out, the first sentence is odd.

In the second, the word you want is "admission" not "permission" but "to top it" is used in a natural way.
