If I only make certain pages SSL, then the verification badge shows that it is not verified. I didn't my customers to think that any part of the site was not safe. I also ran into issues where random security pop ups would occur since it wasn't SSL. So to be honest I figured I would make it all SSL to make sure there was no doubt about the security. I did a redirect so www.setboutique.com would go to https://, and all links on the site are https:// so everything is consistent.

...I don't know if it was the right decision, but so far it has seemed ok and it hasn't slowed down the site too much...
