Howdy from Tennessee, and welcome to BYC! I'm doing the same thing as you: just gearing up to build my first coop. I've found loads of great ideas and info here, and I'm sure you will too. Good luck and God bless!
Welcome, from Connecticut! What you need to do next is get yourself some baby chicks; by the time you're done building your coop, they'll be ready to move into it! Enjoy and let us know if we can help with any questions at all!
