How do I customize my facebook business page?

[babydear]

I am a stay at home mom who just started a arts and crafts business. I am trying to make my business page on facebook look more professional, but I don't know how to customize my page any more than the basic inputting of information and adding photos. I am trying to add a header and order form that links to my email. A discussion forum would be great, too, but its not necessarily needed. Are their apps that I need to add? If so, which ones?
