 You can test that the certificate is working correctly by typing "grid-proxy-init". The command  "voms-proxy-init -voms atlas" will not work yet, since you have register again with VO ATLAS (even if you was already VO member - it seems DOE GRID re-registration resets your VO membership!

 Follow the instructions on that page exactly. When you get to the set where it redirects you to https://lcg-voms.cern.ch:8443/vo/atlas/vomrs you should be using the same browser that you imported the DOE grid certificate or you'll need to import your certificate to the browser you want to use. You can check that it is setup correctly by looking in the bottom left corner and looking for your name. Follow the instructions on that page exactly.
