A few questions..

1. In html, you would comment out a section by surrounding it with:

<!--
html you don't want shown
-->

However, the information will still be there in the source code. So, if a user wants to see what there post count is, they could be sneaky and look at the source code. If you remove it, you should be able to get it back by either reverting the template, clicking on Show Default in the template and finding the code, or clicking on View History in the template and then selecting the current template and the default template and clicking Compare Versions for it to show you the differences.

2. I think so. I'm not sure where else it would show up. Those are the places that immediately come to mind. You could do a search in your templates for "posts" and see what comes up.
