[I am the author of SSL Labs.] I agree with you that SSL Labs currently does not help non-experts very much; the test is still focused on presenting the details, but without guidance. The next version should be very explicit about what should and should not be done.

As for your case, I propose that you follow my advice from the blog post I linked to earlier. It's much easier to do that then to find out exactly why the results are not as you expect.
