The guys from bsdnow.tv did a great job by putting together a tutorial with some more details on a proper Nginx configuration and a very good choice for SSL parameters. There where some parts I didn't know neither and the tutorial is create as always.
If you want to configure a web server with SSL/TLS support and you're not sure what parameters to set for SSL/TLS, watch their tutorial at the end of the episode and you will learn a lot.

If you don't know them yet, take you some time to browser trough their videos!
Beside this you can check your SSL/TLS configuration using the ssllabs test to improve your current settings or check frequently to not miss a newly found vulnerability:https://www.ssllabs.com/ssltest/
