I'll leave CA recommendations to those who deal with them more than I, but if you use Godaddy as a registrar I would urge you to switch to Gandi.net (or namecheap.com if you cannot afford Gandi).
Google is a decent registrar now that I've moved some domains to them... although I don't know if they offer SSL yet directly, I think they recommend a few 3rd parties though.
