Do I need Office 2013 & the premium edition for Visual Studio for my development and production environments?

In the following link http://social.technet.microsoft.com/wiki/contents/articles/15289.sharepoint-2013-best-practices-creating-a-development-environment.aspx it is mentioned that I need to have the following when building my SharePoint 2013 environment:-

1. Office 2013.
2. The premium edition of Visual-Studio 2012.

But my current situation is that I already got Visual-Studio 2012 professional edition based on my previous reading which mentioned that the professional version will have all the required SharePoint templates. So my questions are:-

1. Do I need the Office 2013 and VS premium?
2. And if yes, then should I have office 2013 on both my production and development environments?

Best regards
