Blog post Facebook share pop-up question

I need to know how to:

Set the description to the Summary of the Blog post

Set the title of the page to the title of the Blog Post instead of just ArtsWave.

Set the og:image to the Featured Image

I need to know where to make the changes. I thought maybe this would be done in the Widget designer under "Blog Posts - Single".

Any help would be greatly appreciated!

I figured out how to update the Description shown in the Facebook share pop-up window by updating the Blog Posts widget on the page. 

Edit -> Single Items Settings -> Advanced -> MetaDescriptionField

Added Summary to text box under MetaDescriptionField
