It's up to you what you want to designate your facebook page as. I see a lot of Etsy sellers designate theirs as "Local Business", although that isn't applicable to some of us!
If you want more likes, I suggest joining facebook promotion teams. Team members will "like" you, and networking with them will give you more ideas about your own facebook page.
It's up to you whether you want to allow comments; I do because I like to know who's visiting my page and network with other Etsy sellers.
Let me know if you have any other questions about facebook, I love to help!
Oh and if you want to visit me :)
