Yes! Your clear and concise instructions worked...almost. The problem was the password. When using openssl to create the p12 file, I needed to use the keystore password (changeit). Once I did that, I was able to import the file (using portecle) and the server and admin console would start without a problem.
Unfortunately at this point, https still didn't work (although at least it would fail quickly rather than hang). On a whim I decided to import the CA certificate (I went to the CA website and downloaded) and this worked.
So, unlike your experience, I needed both the p12 key file and CA certificate in the keystore.
One last note...I did have to restart Firefox on my test PC for all this work.
