How can I correctly install, and then check, a schema into my wordpress site? I tried to do it but seem to have doubled up on some of the information (copyright) and also am now sure if I have accomplished the SEO purposes I had in mind.

I would appreciate help with this!

On WordPress platform, you need to follow these steps to install schema because WordPress has a problem with microdata. The nerdy reason has to do with WordPress outputting microformatting markup in the ul_list_comments. That's geek speak for the two different markup languages don't play well together.

The result is that WordPress strips the microdata from the page. Until wordpress fixes this issue, you will have to choose a workaround.

There are two solutions to this problem:

Disable the visual editor (or place markup in the HTML editor and then publish without moving back to visual).- This is a workaround. The downside to this is if you decide to go back and re-edit the post after the fact, you will have to re-input the data.
Use a plug-in that will do this for you- There are two. One is stand alone called schema for wordpress. The other is an SEO plugin (which you can disable everything but what you need) called SEO Ultimate.

Thank you!
