I uploaded mine as Word docs (.doc, IIRC). Createspace says you can use either. I'm pretty sure they have a template you can download (it's been a while since I did mine - going from memory).

Lastly, does it matter which version I publish first, the paperback or the KDP (ebook) version?
I'd go with ebook, just because Amazon lets you actually set a release date in advance. Createspace just does it when you upload, but it takes a bit longer.
