Google released Google+ Pages just a few months ago, so everyone is still getting familiar with how to use it effectively for business and personal use. I came across a blog post that was posted in December 2011 which explains how to maintain your Google+ Pages and goes over everything in detail.
There is a video that goes over maintaining your Google+ page, Multiple Administrators and Ownership Transfer, Notification Settings. Also is explain how +1 and circle count are unified with your Google+ Page.
