I'd probably look at us suggesting some css to see if we can move the positioning of the zentools title - if you needed that
Yes it does appear we only added the page heading to categories
If you wanted "It's About Us" in a file name that would be a problem - I don't think Joomla would allow you to use media manager to upload and even uploading via ftp might not work
Depending on the flexiblity you need for the site and who would be working with / updating it - a work around might be to try with a k2 category but use it as a single article by faking it using the k2 settings.
Another work around might be to try with zentools2 as this has more flexibility with titles and content sources but would probably need css adjustments
