I understand that none of the coding is done for the layouts or prototyping, but that you can export and use the templates in Dreamweaver much like Photoshop Art Boards... but I have found no tutorials that explain just how to do that unless it is in Photoshop. The design folders all have the assets from the layouts I've made, and maybe I should try to build a website using Photoshop and Dreamweaver first, but then exactly what was the point of me using XD?,
And from a development side, how do I go about coding different display types so that each viewport looks how it's supposed to? I've signed up for Lynda.com and believe me, If I have made it this far I know how to dig around, I just could use anybody's help to point in the right direction.
I want to be able to use Adobe XD to create layouts and quickly develop sites that look well across all devices.
The answer to your question is probably in this thread: Whats the difference between Adobe XD and Adobe Muse
Specifically, though, you should think of Adobe XD as a place to make rapid iterations on your designs before implementing. I actually do a lot of ideation in XD before even beginning with any code in order to make sure I know what I'm building and what it's going to look like.
