Hi,
1. I don't have that problem with the webshop text on your website. Wouldn't that be because of your internet connection being slow ? In that case, the browser might start to display what it already loaded from the page, while waiting to get the rest of the page data.
You could avoid that displaying a loading bar until the page is fully loaded with some modification to your template.
Here is a page about that:

2. Regarding the heading, I don't see why that wouldn't work. I wanted to look again at the links on your website but they don't work anymore. And if I check your website, I see that you have the old method with the module and it seems to work on the few pages I looked at.
