Using VSTO, I've created a custom tab in the Ribbon designer and added some groups and button controls there. When user clicks one of the buttons, I'd like to connect to a SharePoint site and open a word document from it in Word (an instance is already open). I'm able to connect to the SharePoint site already and have the URLs to the documents I want to open.
But how can I actually load these documents into Word? I'm already in the code-behind in Word, so how can I target the Word instance I'm in and open a file there?
Thanks in advance.

You would have to use the Word API to open a document. See this link for a reference. You may have to update it based on the API version you use.
